How to pronounce Irish names

Irish names are not spelled strangely. They are spelled in Irish, which uses the same twenty-odd letters as English for a different set of sounds — so it pairs them up. Learn seven pairs and most of the language opens.

The seven rules that do most of the work
bh, mh
v — or w in the middle of a word
Siobhán “shi-VAWN”Niamh “NEEV”Caoimhe “KWEE-va”
dh, gh
silent, or a soft y at the start
Tadhg “TYGE”Aodh “AY”Pádraig “PAW-drig”
th
h — never the English th
Caitlín “kat-LEEN”Rathnait “RA-nit”
s before e or i
sh
Seán “SHAWN”Saoirse “SEER-sha”Sinéad “shi-NAYD”
ch
the back-of-the-throat sound in loch — not ch as in church
Lorcán “LOR-kawn”Conchobhar “KON-a-khoor”
ao
ee, or ay in Munster
Aoife “EE-fa”Saoirse “SEER-sha”Caoimhín “KWEE-veen”
á é í ó ú (the fada)
a long vowel — and never optional
Seán “SHAWN”Róisín “ro-SHEEN”Órlaith “OR-la”
Why so many letters look silent Irish consonants come in pairs, broad and slender, and the language has more of them than the Latin alphabet has letters. So the spelling uses the vowels on either side to say which kind a consonant is: i and e mark a slender one, a, o and u a broad one. Those vowels are doing grammatical work rather than making a sound of their own, which is why a name can look far longer than it sounds. The rule has a name in Irish (caol le caol, leathan le leathan, slender with slender, broad with broad) and it is why a vowel often has to be added on both sides of a consonant just to keep the spelling legal.
One thing to know before you correct anybody Irish has three main dialect groups (Ulster, Connacht and Munster) and many names are said differently in each. The respellings here give the pronunciation most commonly heard in Irish English; where a well-known variant exists, both are shown.
