Meaning & History
Mór is an Irish feminine name meaning "great" (from the Irish word mór). It was a popular name in medieval Ireland, especially as an alternative to Máire (the Irish form of Mary). Due to the belief that Máire was too sacred for everyday use—being the name of the Virgin Mary—many parents chose Mór or its diminutives instead. This taboo on using Mary's name directly occurred in several Christian cultures; in Ireland, Mór served as a respectful substitute while still honoring the Virgin.
Etymology and Historical Usage
Mór derives directly from the Irish adjective mór meaning "great, large." It was used as a given name from at least the early medieval period. The name appears in Irish annals and genealogies, often borne by noblewomen and saints. Over time, variants emerged to differentiate widespread use: Móirín (diminutive, meaning "little great one") and Moreen (anglicized form). Similarly, Scottish Gaelic developed Mòr and Mòrag from the same root.
Cultural Context
The replacement of Máire by Mór reflects a broader onomastic pattern in Christianity where names deemed sacred were avoided for ordinary children. For example, in some Orthodox traditions, the name Panagia (All-Holy) was not used as a personal name. In Ireland, this reverence led to creative alternatives. The name Máire itself is derived from Mary, the English form of Maria, which ultimately comes from Hebrew Miryam. The exact meaning of Miryam is uncertain but may be Egyptian for "beloved" or Hebrew for "wished-for child." Despite the honor paid to the Virgin Mary, her name was considered too holy at times, prompting the rise of cognates like Mór.
Modern Usage
While Mór itself is now rare, its diminutives—especially Móirín and its Anglicized form Moreen—are still occasionally used in Ireland and the Irish diaspora. The name is almost exclusively female. Its revival remains limited, but it retains historical and cultural significance within Irish onomastics.
