Character Name

Lasair

Meaning — From the Old Irish "lasair" meaning "flame" or "blaze". Saint Lasair was a 6th-century Irish saint, daughter of the king of Connacht, whose feast day is celebrated in March. The name is strikingly evocative — flame as a feminine quality, the brightness that illuminates and warms but can also consume. It belongs to the tradition of Irish nature-names that describe a quality of being rather than a social role.·Old Irish origin·Female·LAS-ir

Lasair Lasair projects an incandescent energy — characters with this name are vivid presences whose intensity cannot be moderated to a comfortable level, who light up situations and sometimes ignite them. The flame quality suggests brilliance that requires tending and direction: extraordinary heat and light that, undirected, becomes dangerous and that directed becomes transformative. A name for characters who change every situation they enter.

More Old Irish names

Ciarán

Derived from the Old Irish "ciar" meaning "dark", "black", or "dark-haired", with the diminutive suffix "-án" giving "little dark one". The name was borne by two major Irish saints: Saint Ciarán of Clonmacnoise (c. 512–545 AD), who founded the great monastery of Clonmacnoise on the River Shannon — one of the most important centres of early medieval learning in Europe — and Saint Ciarán of Saighir, one of the earliest Irish saints.

Caoimhín

The Old Irish form of Kevin, meaning "gentle birth" or "kind and gentle", from the Old Irish elements "caomh" (gentle, kind, dear) and "gin" (birth). Saint Caoimhín of Glendalough (c. 498–618 AD) was one of the patron saints of Dublin, a hermit who lived in the Wicklow Mountains before founding the great monastery of Glendalough — one of Ireland's most celebrated sacred sites and centres of learning.

Cormac

Derived from the Old Irish "corb" meaning "chariot" (or possibly "raven") and "mac" meaning "son" — giving the meaning "son of the chariot" or possibly "charioteer's son". The name was borne by the legendary High King Cormac mac Airt, considered one of Ireland's greatest and wisest kings, whose court at Tara became associated with an idealised golden age of justice and prosperity.

Grainne

Possibly derived from the Old Irish "grán" meaning "grain" or "gráin" meaning "hatred" or "terror", though the exact etymology remains debated. In Irish legend, Gráinne is the passionate, wilful daughter of the High King Cormac mac Airt who refuses her arranged marriage to the aging hero Fionn mac Cumhaill and flees with the young warrior Diarmuid — one of Ireland's great romantic epics.

Oisín

Derived from the Old Irish "os" meaning "deer" combined with the diminutive suffix "-ín", giving the meaning "little deer" or "young fawn". In Irish mythology, Oisín was the greatest poet and warrior of the Fianna, son of the legendary hero Fionn mac Cumhaill. His mother Sadhbh had been transformed into a deer, and so the name carries a poetic link to his origins.

Tadhg

From the Old Irish "Tadg" or "Tadc", meaning "poet", "philosopher", or "storyteller". The name carries deep associations with the bardic tradition of Celtic Ireland and was borne by numerous kings, saints, and mythological figures throughout Irish history. Its anglicised forms — Thaddeus, Timothy, Teague — spread widely through the Irish diaspora, though none capture the full resonance of the original.
