Reading Irish spelling
Irish Gaelic uses the same alphabet as English, but the letters follow different rules. The pairs bh and mh usually sound like v or w, dh and gh often go silent or soften, and the accent called a fada makes a vowel long. Once you learn a few patterns, names that look impossible become easy.
Many famous Irish names now have English spellings too. Seán is also written Shawn, Ciarán is Kieran, and Méabh is Maeve. Pick the Gaelic form for a traditional feel and the English form if readers need help.
- Niamh: NEEV. Sadhbh: SIVE (rhymes with five).
- Caoimhe: KEE-va. Saoirse: SEER-sha.
- Oisín: uh-SHEEN. Tadhg: TIGE, like the first part of tiger.
- Siobhán: shiv-AWN. Dónal: DOH-nal.
O', Mac and Irish nicknames
The O' in a surname comes from Ó, meaning grandson or descendant, and Mac means son. So O'Brien means descendant of Brian, a nod to the high king Brian Boru, and McCarthy means son of Carthach. During English rule many families dropped the O' or Mac, and many added it back in the late 1800s and early 1900s as pride in Irish roots grew.
In everyday Ireland, people often go by a nickname. Pádraig becomes Paddy or Podge, Séamus becomes Shay, Michael becomes Mick, and Seán becomes Seánie. A surname can turn into a nickname too, so a lad named Murphy might just be Murph to his mates.
Example names and what makes them work

| Tadhg O'Sullivan | Tadhg means poet; O'Sullivan is common in Cork and Kerry. |

Tips for picking the right name
- Add a short pronunciation note in your book's first chapter if you use a name like Caoimhe or Sadhbh.
- Keep the fadas in names like Seán and Róisín; without them the sound changes.
- Give your Irish character a nickname their friends use, such as Shay for Séamus.
- Use O' and Mac surnames for old Gaelic families, and names like Walsh or Burke for Norman-Irish roots.
- Pair a mythic first name like Fionn or Niamh with a common surname so it still feels real.
Common questions
What are popular Irish boy names right now?
In recent years Jack, Noah, James, Rían, Fionn, Oisín, Cillian and Tadhg have all been popular in Ireland. Classic names like Conor, Seán and Darragh are still widely used too.
What does the O' in an Irish surname mean?
It comes from the Irish word Ó, meaning grandson or descendant. O'Neill means descendant of Niall. Mac, written Mc in many families, means son, as in McGrath or MacNamara.
Why are Irish names spelled so differently from how they sound?
Irish Gaelic has its own spelling rules. Letter pairs like bh and mh often make a v sound, and some letters go silent. The spelling is regular within Irish; it only looks odd when read with English rules.
