Gaelic personal names come from the Goidelic languages of Ireland, Scotland, and the Isle of Man. They show consistent phonological spelling: lenition is written with h after consonants (bh, mh, dh, gh), and pronunciation depends on broad vs slender vowels (a, o, u vs e, i). Irish uses acute accents (fada) and Scottish Gaelic uses grave accents to mark vowel length. Common structural patterns include patronymic prefixes Mac/Mc “son of” and Ó “descendant of,” with feminine forms Ní (Irish) and Nic (Scottish Gaelic). Diminutives often end in -án or -ín (Irish) and -an (Scottish Gaelic).
Lexical elements are drawn from Old and Middle Gaelic: fionn “fair,” dubh “dark,” cath “battle,” rí “king,” cú “hound,” and religious theophoric forms such as Maol- and Gille-/Giolla- “devotee of [a saint].” Christianization and saints’ cults introduced many personal names and reshaped earlier ones. Historical anglicization produced parallel forms, while modern usage in Ireland and Scotland favors standardized Gaelic spellings alongside established English variants.
