Dom is an honorific prefixed to the given name. It derives from the Latin Dominus.
It is used in English for certain Benedictine (including some communities which follow the Rule of St. Benedict) and Carthusian monks, and for members of certain communities of Canons Regular. Examples include Benedictine monks of the English Benedictine Congregation (e.g. Dom John Chapman, late Abbot of Downside). Since the Second Vatican Council, the title can be given to any monk (lay or ordained) who has made a solemn profession. The equivalent title for a nun is "Dame" (e.g. Dame Laurentia McLachlan, late Abbess of Stanbrook, or Dame Felicitas Corrigan, author).
In Portugal and Brazil, Dom (pronounced [ˈdõ]) is used for certain hierarchs of the Roman Catholic and Greek Orthodox Churches, and for laymen who belong to the royal and imperial families (for example the House of Aviz in Portugal and the House of Braganza in Portugal and Brazil).[1] It was also accorded to members of families of the titled Portuguese nobility.[2] Unless ennobling letters patent specifically authorised its use, Dom was not attributed to members of Portugal's untitled nobility: Since hereditary titles in Portugal descended according to primogeniture, the right to the style of Dom was the only apparent distinction between cadets of titled families and members of untitled noble families.[2] Dom has historically been used on occasions in French, as an honorific for Benedictine monks, such as the famous Dom Pérignon. The feminine form, Dona, is a common honorific reserved for women, such as the First Lady of Brazil. In Portugal the feminine version of the honorific is more broadly attributed to women than Dom is to men.[2]
An article by Dom Aidan Bellenger about Buckfast Abbey was published on 2 June 2018 in ‘’The Tablet’’, Britain’s leading Catholic journal. However, by editorial error the article was attributed to “Dominic Aidan Bellenger”[3]. It is not the only time that this former Abbot of Downside’s honorific has been misconstrued.
