The internal classification of the Romance languages is a complex and sometimes controversial topic which may not have one single answer. Several classifications have been proposed, based on different criteria.

The comparative method used by linguists to build family language trees is based on the assumption that the member languages evolved from a single proto-language by a sequence of binary splits, separated by many centuries. With that hypothesis, and the glottochronological assumption that the degree of linguistic change is roughly proportional to elapsed time, the sequence of splits can be deduced by measuring the differences between the members.

However, the history of Romance languages, as we know it, makes the first assumption rather problematic. While the Roman Empire lasted, its educational policies and the natural mobility of its soldiers and administrative officials probably ensured some degree of linguistic homogeneity throughout its territory. Even if there were differences between the Vulgar Latin spoken in different regions, it is doubtful whether there were any sharp boundaries between the various dialects. On the other hand, after the Empire's collapse, the population of Latin speakers was separated—almost instantaneously, by the standards of historical linguistics—into a large number of politically independent states and feudal domains whose populations were largely bound to the land. These units then interacted, merged and split in various ways over the next fifteen centuries, possibly influenced by languages external to the family (as in the so-called Balkan language area).

In summary, the history of Latin and Romance-speaking peoples can hardly be described by a binary branching pattern; therefore, one may argue that any attempt to fit the Romance languages into a tree structure is inherently flawed.^[1] In this regard, the genealogical structure of languages forms a typical linkage.^[2]

On the other hand, the tree structure may be meaningfully applied to any subfamilies of Romance whose members did diverge from a common ancestor by binary splits. That may be the case, for example, of the dialects of Spanish and Portuguese spoken in different countries, or the regional variants of spoken standard Italian (but not the so-called "Italian dialects", which are distinct languages that evolved directly from Vulgar Latin).

The two main avenues to attempt classifications are historical and typological criteria:^[3]

• Historical criteria look at the Romance languages' former development. For example, a widely employed model divided the Romance-speaking world between West and East based on whether plural nouns end in -s or in a vowel. Researchers have highlighted this is mainly valid from a historical point of view as the change appeared in Antiquity in the East (Italo-Romance, Dalmatian and Eastern Romance), while in the West plural nouns ending in -s were preserved past this stage but could be lost by more recent changes (such as aspiration of word-final -s in some varieties of Spanish and its phonetic loss in French).^[4] Another criterion taken into account is the distinction between conservative and innovative/progressive Romance languages. Generally, the Gallo-Romance languages (discussed further below) form the core "innovative" languages, with standard French often considered the most innovative of all. The phenomenon is attributed to language development in the Carolingian Empire with Northern Italy and Catalan region representing marginal areas of distribution. For example, Catalan, up to the thirteenth century, used the Romance writing modes common in the Occitan area. This created a contrast with the languages near the periphery (which include Spanish, Portuguese, Italian and Romanian) which are deemed as "conservative".^[5] Sardinian is generally acknowledged as the most conservative Romance languages, at least from a phonetic point of view. Dante famously denigrated the Sardinians for the conservativeness of their speech, remarking that they imitate Latin "like monkeys imitate men".^[6][7] According to Gerhard Rohlfs France replaced Italy as a centre of diffusion of innovations around the sixth century.^[8]
• Typological criteria measure the structural features of Romance languages, mainly in synchrony. For example, the identification of the La Spezia–Rimini Line line, which is generally accepted as the main isogloss for consonantal lenition in Romance languages and which runs across north-central Italy just to the north of the city of Florence (whose speech forms the basis of standard Italian). In this scheme, "East" includes the languages of central and southern Italy, and the Eastern Romance languages in Romania, Greece, and elsewhere in the Balkans; "West" includes the languages of Portugal, Spain, France, northern Italy and Switzerland.^[9] Sardinian does not fit at all into this sort of division.^[10] Further expansions on this are discussed below.

By applying the comparative method, some linguists have concluded that Sardinian became linguistically developed separately from the remainder of the Romance languages at an extremely early date.^[11] Among the many distinguishing features of Sardinian are its articles (derived from Latin IPSE instead of ILLE) and lack of palatalization of /k/ and /ɡ/ before /i e ɛ/^[12] and other unique conservations such as domo ‘house’ (< domo).^[13] Sardinian has plurals in /s/ but post-vocalic lenition of voiceless consonants is normally limited to the status of an allophonic rule, which ignores word boundaries (e.g. [k]ane 'dog' but su [ɡ]ane or su [ɣ]ane 'the dog'), and there are a few innovations unseen elsewhere, such as a change of /au/ to /a/.^[14] This view is challenged in part by the existence of definite articles continuing ipse forms (e.g. sa mar 'the sea') in some varieties of Catalan, best known as typical of Balearic dialects. Sardinian also shares develarisation of earlier /kw/ and /ɡw/ with Romanian: Sard. abba, Rum. apă 'water'; Sard. limba, Rom. limbă 'language' (cf. Italian acqua, lingua).

According to this view, the next split was between Common Romanian in the east, and the other languages (the Italo-Western languages) in the west. One of the characteristic features of Romanian is its retention of three of Latin's seven noun cases. The third major split was more evenly divided, between the Italian branch, which comprises many languages spoken in the Italian Peninsula, and the Gallo-Iberian branch.

However, this is not the only view. Another common classification begins by splitting the Romance languages into two main branches, East and West. The East group includes Romanian, the languages of Corsica and Sardinia,^[9] and all languages of Italy south of a line through the cities of Rimini and La Spezia (see La Spezia–Rimini Line). Languages in this group are said to be more conservative, i.e. they retained more features of the original Latin.

The West group split into a Gallo-Romance group, which became the Oïl languages (including French), Gallo-Italian, Occitan, Franco-Provençal and Romansh, and an Iberian Romance group which became Spanish and Portuguese.

A three-way division is made primarily based on the outcome of Vulgar Latin (Proto-Romance) vowels:

Italo-Western is in turn split along the so-called La Spezia–Rimini Line in northern Italy,^[15] which is a bundle of isoglosses separating the central and southern Italian languages from the so-called Western Romance languages to the north and west. Some noteworthy differences between the two are:

• Phonemic lenition of intervocalic stops, which happens to the northwest but not to the southeast.
• Degemination of geminate stops (producing new intervocalic single voiceless stops, after the old ones were lenited), which again happens to the northwest but not to the southeast.
• Deletion of intertonic vowels (between the stressed syllable and either the first or last syllable), again in the northwest but not the southeast.
• Use of plurals in /s/ in the northwest vs. plurals using vowel change in the southeast.
• Development of palatalized /k/ before /e,i/ to /(t)s/ in the northwest vs. /tʃ/ in the southeast.
• Development of /kt/, which develops to /xt/ > /it/ (sometimes progressing further to /tʃ/) in the northwest but /tt/ in the southeast.

Recent scholarship argues for a more nuanced view. All of the "southeast" characteristics apply to all languages southeast of the line, and all of the "northwest" characteristics apply to all languages in France and (most of) Spain yet the Gallo-Italic languages are somewhere in between. These languages do have the "northwest" characteristics of lenition and loss of gemination however other seemingly clear boundaries are often obscured by local variations:^[16]

• The Gallo‒Italic languages have vowel-changing plurals rather than /s/ plurals.
• The Lombard language in north-central Italy and the Rhaeto-Romance languages have the "southeast" characteristic of /tʃ/ instead of /(t)s/ for palatalized /k/.
• The Venetian language in northeast Italy and some of the Rhaeto-Romance languages have the "southeast" characteristic of developing /kt/ to /tt/.
• Lenition of post-vocalic /p t k/ is widespread as an allophonic phonetic realization in Italy below the La Spezia-Rimini line, including Corsica and most of Sardinia.

The likely cause for this partition is that the focal point of innovation was located in central France and was related directly to the level of Carolingian influence, from which a series of innovations spread out as areal changes. The La Spezia–Rimini Line would then represent the farthest point to the southeast that these innovations reached, corresponding to the northern chain of the Apennine Mountains, which cuts straight across northern Italy and forms a major geographic barrier to further language spread. This would explain why some of the "northwest" features (almost all of which can be characterized as innovations) end at differing points in northern Italy, and why some of the languages in geographically remote parts of Spain (in the south, and high in the Pyrenees) are lacking some of these features. It also explains why the languages in France (especially standard French) seem to have innovated earlier and more extensively than other Western Romance languages.^[17]

On top of this, the medieval Mozarabic language in southern Spain, at the far end of the "northwest" group, may have had the "southeast" characteristics of lack of lenition and palatalization of /k/ to /tʃ/.^[18] Certain languages around the Pyrenees (e.g. some highland Aragonese dialects) also lack lenition, and northern French dialects such as Norman and Picard have palatalization of /k/ to /tʃ/ (although this is possibly an independent, secondary development, since /k/ between vowels, i.e. when subject to lenition, developed to /dz/ rather than /dʒ/, as would be expected for a primary development).^[19]

Many of the "southeast" features also apply to the Eastern Romance languages (particularly, Romanian), despite the geographic discontinuity. Examples are lack of lenition, maintenance of intertonic vowels, use of vowel-changing plurals, and palatalization of /k/ to /tʃ/. This has led some researchers, following Walther von Wartburg, to postulate a basic two-way east–west division, with the "Eastern" languages including Romanian and central and southern Italian, although this view is troubled by the contrast of numerous Romanian phonological developments with those found in Italy below the La Spezia-Rimini line. Among these features, in Romanian geminates reduced historically to single units, and /kt/ developed into /pt/, whereas in central and southern Italy geminates are preserved and /kt/ underwent assimilation to /tt/.^[20]

Linguists like Jean-Pierre Chambon claim that the various regional languages did not evolve in isolation from their neighbours; on the contrary, they see many changes propagating from the more central regions (Italy and France) towards the periphery (Iberian Peninsula and Romania).^[21] These authors see the Romance family as a linkage rather than a tree-like family, and insist that the Wave model is better suited than the Tree model for representing the history of Romance.

In a study by linguist Mario Pei (1949), the degrees of phonological modification of vowels of the Romance languages with respect to the ancestral Latin were found to be as follows^[22][23]

• Sardinian: 8%
• Italian: 12%
• Spanish: 20%
• Romanian: 23.5%
• Occitan: 25%
• Portuguese: 31%
• French: 44%

Part of the difficulties met in classifying Romance languages is due to the seemingly messy distribution of linguistic innovations across members of the Romance family. While this is a problem for followers of the dominant Tree model, this is in fact a characteristic typical of linkages and dialect continuums generally: this has been an argument for approaching this family with the tools based on the Wave model, including dialectology and Historical glottometry.

What follows is a sample of some significant linguistic traits (innovations since Vulgar Latin) that run across the Romance linkage.

The differences among Romance languages occur at all levels, including the sound systems, the orthography, the nominal, verbal, and adjectival inflections, the auxiliary verbs and the semantics of verbal tenses, the function words, the rules for subordinate clauses, and, especially, in their vocabularies. While most of those differences are clearly due to independent development after the breakup of the Roman Empire (including invasions and cultural exchanges), one must also consider the influence of prior languages in territories of Latin Europe that fell under Roman rule, and possible heterogeneity in Vulgar Latin itself.

Romanian, together with other related languages, like Aromanian, has a number of grammatical features which are unique within Romance, but are shared with other non-Romance languages of the Balkans, such as Albanian, Bulgarian, Greek, Macedonian, Serbo-Croatian and Turkish. These include, for example, the structure of the vestigial case system, the placement of articles as suffixes of the nouns (cer = "sky", cerul = "the sky"), and several more. This phenomenon, called the Balkan language area, may be due to contacts between those languages in post-Roman times.

Some Romance languages form plurals by adding /s/ (derived from the plural of the Latin accusative case), while others form the plural by changing the final vowel (by influence of Latin nominative plural endings, such as /i/) from some masculine nouns.

• Plural in /s/: Portuguese, Galician, Spanish, Catalan,^[24] Occitan, Sardinian, Friulian, Romansh.
  • Special case of French: Falls into the first group historically (and orthographically), but the final -s is no longer pronounced (except in liaison contexts), meaning that singular and plural nouns are usually homophonous in isolation. Many determiners have a distinct plural formed by both changing the vowel and allowing /z/ in liaison.
• Vowel change: Italian, Neapolitan, Sicilian, Romanian.

Some Romance languages use a version of Latin plus, others a version of magis.

• Plus-derived: French plus /plys/, Italian più /pju/, Sardinian prus /ˈpruzu/, Piedmontese pi, Lombard pu, Ligurian ciù, Neapolitan chiù, Friulian plui, Romansh pli, Venetian pi. In Catalan pus /pus/ is exclusively used in negative statements in the Mallorcan dialect, and "més" is the word mostly used.
• Magis-derived: Galician and Portuguese (mais; medieval Galician-Portuguese had both words: mais and chus), Spanish (más), Catalan (més), Venetian (massa or masa, "too much") Occitan (mai), Romanian (mai).

Although the Classical Latin word for "nothing" is nihil, the common word for "nothing" became nulla in Italian (from neuter plural nulla, "no thing",^[25] or from nulla res;^[26] Italian also has the word "niente"), nudda [ˈnuɖːa] in Sardinian, nada in Spanish, Portuguese, and Galician (from (rem) natam, "thing born";^[27] Galician also has the word "ren"), rien in French, res in Catalan, cosa and res in Aragonese, ren in Occitan (from rem, "thing",^[28] or else from nominative res),^[29] nimic in Romanian, nagut in Romansh, gnente in Venetian and Piedmontese, gnent and nagott in Lombard, and nue and nuie in Friulian. Some argue that most roots derive from different parts of a Latin phrase nullam rem natam ("no thing born"), an emphatic idiom for "nothing".^{[citation needed]} Meanwhile, Italian and Venetian niente and gnente would seem to be more logically derived from Latin ne(c) entem ("no being"), ne inde or, more likely, ne(c) (g)entem, which also explains the French cognate word néant.^[30][31] The Piedmontese negative adverb nen also comes directly from ne(c) (g)entem,^[26] while gnente is borrowed from Italian.

Romanian constructs the names of the numbers 11–19 by a regular Slavic-influenced pattern that could be translated as "one-over-ten", "two-over-ten", etc. All the other Romance languages use a pattern like "one-ten", "two-ten", etc. for 11–15, and the pattern "ten-and-seven, "ten-and-eight", "ten-and-nine" for 17–19. For 16, however, they split into two groups: some use "six-ten", some use "ten-and-six":^[32]

• "Sixteen": Italian sedici, Catalan and Occitan setze, French seize, Venetian sédexe, Romansh sedesch, Friulian sedis, Lombard sedas / sedes, Franco-Provençal sèze, Sardinian sèighi, Piedmontese sëddes (sëddes is borrowed from Lombard and replaced the original sëzze since the 18th century, such as the numbers from 11 to 16, onze but now óndes, dose but now dódes, trëzze but now tërdes, quatòrze but now quatòrdes, quinze but now quìndes).
• "Ten and six": Portuguese dezasseis or dezesseis, Galician dezaseis (decem ac sex), Spanish dieciséis (Romance construction: diez y seis), the Marchigiano dialect digissei.
• "Six over ten": Romanian șaisprezece (where spre derives from Latin super).

Classical Latin uses the "one-ten" pattern for 11–17 (ūndecim, duodecim, ... , septendecim), but then switches to "two-off-twenty" (duodēvigintī) and "one-off-twenty" (ūndēvigintī). For the sake of comparison, note that many of the Germanic languages use two special words derived from "one left over" and "two left over" for 11 and 12, then the pattern "three-ten", "four-ten", ... , "nine-ten" for 13–19.

The verbs derived from Latin habēre "to have", tenēre "to hold", and esse "to be" are used differently in the various Romance languages, to express possession, to construct perfect tenses, and to make existential statements ("there is").^[33][34] If we use T for tenēre, H for habēre, and E for esse, we have the following distribution:

• HHE: Romanian, Italian, Gallo-Italic languages.
• HHH: Occitan, French, Romansh, Sardinian.
• THH: Spanish, Catalan, Aragonese.
• T-H/T-T: Portuguese.

For example:

Ancient Galician-Portuguese used to employ the auxiliary H for permanent states, such as Eu hei um nome "I have a name" (i.e. for all my life), and T for non-permanent states Eu tenho um livro "I have a book" (i.e. perhaps not so tomorrow), but this construction is no longer used in modern Galician and Portuguese. Portuguese also uses the T verb even in the existential sense, e.g. Tem água no copo "There is water in the glass". Sardinian employs both H and E for existential statements, with different degrees of determination.

Languages that have not grammaticalised *tenēre have kept it with its original sense "hold", e.g. Italian tieni il libro, French tu tiens le livre, Romanian ține cartea, Friulian Tu tu tegnis il libri "You're holding the book". The meaning of "hold" is also retained to some extent in Spanish and Catalan.

Romansh uses, besides igl ha, the form i dat (literally: it gives), calqued from German es gibt.

Some languages use their equivalent of 'have' as an auxiliary verb to form the compound forms (e. g. French passé composé) of all verbs; others use 'be' for some verbs and 'have' for others.

• 'have' only: Standard Catalan, Spanish, Romanian, Sicilian.
• 'have' and 'be': Occitan, French, Sardinian, Italian, Northern-Italian languages (Piedmontese, Lombard, Ligurian, Venetian, Friulan), Romansh, Central Italian languages (Tuscan, Umbrian, Corsican) some Catalan dialects (although such usage is recessing in those).

In the latter type, the verbs which use 'be' as an auxiliary are unaccusative verbs, that is, intransitive verbs that often show motion not directly initiated by the subject or changes of state, such as 'fall', 'come', 'become'. All other verbs (intransitive unergative verbs and all transitive verbs) use 'have'. For example, in French, J'ai vu or Italian ho visto 'I have seen' vs. Je suis tombé, sono caduto 'I have (lit. am) fallen'. Note, however, the difference between French and Italian in the choice of auxiliary for the verb 'be' itself: Fr. J'ai été 'I have been' with 'have', but Italian sono stato with 'be'. In Southern Italian languages the principles governing auxiliaries can be quite complex, including even differences in persons of the subject. A similar distinction exists in the Germanic languages, which share a language area^{[citation needed]}; German, Dutch, Danish and Icelandic use 'have' and 'be', while English, Norwegian and Swedish use 'have' only (although in modern English, 'be' remains in certain relic phrases: Christ is risen, Joy to the world: the Lord is come).

"Be" is also used for reflexive forms of the verbs, as in French j'ai lavé 'I washed [something]', but je me suis lavé 'I washed myself', Italian ho lavato 'I washed [something]' vs. mi sono lavato 'I washed myself'.

Tuscan uses si forms identical to the 3rd person reflexive in a usage interpreted as 'we' subject, triggering 'be' as auxiliary in compound constructions, with the subject pronoun noi 'we' optional. If the verb employed is one that otherwise selects 'have' as auxiliary, the past participle is unmarked: si è lavorato = abbiamo lavorato 'we (have) worked'. If the verb is one that otherwise selects 'be', the past participle is marked plural: si è arrivati = siamo arrivati 'we (have) arrived'.
