How to pronounce Irish names

The single most useful thing to understand about Irish names is that they are not spelled badly. Irish is a separate language with its own orthography, and that orthography is considerably more consistent than English's. Caoimhe looks unpredictable only if you assume the letters are meant to be read as English. Read as Irish, it is exactly as predictable as cat.

That reframing matters practically, because it means a handful of rules covers almost every name you will meet. You do not have to memorise hundreds of names individually — you have to learn about six letter combinations, and after that most names read themselves.

Irish consonants come in two varieties, traditionally called broad and slender. A broad consonant is made with the tongue pulled back; a slender one is made with the tongue pushed forward, giving it a faint y-quality. The difference is meaningful in Irish the way the difference between /p/ and /b/ is meaningful in English.

Irish marks this in writing with the vowels around the consonant. A consonant next to a, o or u is broad; a consonant next to e or i is slender. And here is the payoff: those vowels are often not pronounced as vowels at all. They are there to tell you about the consonant.

This is why Gráinne has an i that you never hear as a separate sound — it is marking the n as slender, which is why the ending comes out closer to -nya. Once you know the extra vowels are consonant labels, Irish names stop looking over-supplied with letters.

This one combination unlocks more Irish names than anything else. A b or an m followed by an h is not two sounds — it is a single letter that has been softened, and in most positions it comes out as v (sometimes w next to a broad vowel).

Siobhán is shiv-AWN, Niamh is NEEV, Caoimhe is KEE-va. In each case the h is not being pronounced and is not silent either — it is a modifier attached to the letter before it, exactly as it is in English sh and th.

Between vowels, mh sometimes disappears entirely rather than becoming a v, which is why Domhnall is DOH-nal. That is the main irregularity in this rule.

A slender s — one sitting next to an e or an i — is pronounced /ʃ/, the sh of ship. A broad s, next to a, o or u, stays as an ordinary /s/. This one rule accounts for a large share of Irish names beginning with S, and for the sh in the middle of several others.

Seán is SHAWN because the e makes the s slender. Sinéad is shi-NAYD for the same reason. And Saoirse, Róisín and Aisling all carry an internal sh that the spelling signals with an adjacent i.

Four smaller rules finish the set.

ao is a long ee. It is one vowel sound, not two. Aoife is EE-fa, Caoimhe is KEE-va, Saoirse begins SEER-.

dh and gh are usually silent or absorbed. They mark a softened consonant that in most modern positions has faded out, often lengthening the vowel next to it instead. This is the whole story of Tadhg: t, a long i sound from adh, then g — TIEG.

c and g are always hard. Irish has no soft c or soft g, so Cian, Ciarán, Cillian and Caoimhe all begin with a k sound. There is no context in which Irish c is /s/.

The fada (´) marks a long vowel and usually the stress. Seán, Sinéad, Pádraig, Róisín, Ciarán. When the accent is dropped in English contexts — Sean, Sinead, Padraig — the information about vowel length goes with it, which is a common source of confusion for readers who have only ever seen the stripped spelling.

Saoirse is the clearest case. The Irish pronunciation is close to SEER-sha. Saoirse Ronan, the best-known bearer of the name internationally, says SUR-sha and has explained it as rhyming with inertia. SOR-sha is also widely used. All three are in circulation, and none of them is a mistake — they are a name travelling between two languages.

Niall splits similarly between NYE-al and NEEL, and Oisín between uh-SHEEN and OSH-een. In every one of these cases the resolution is the same, and it is the general rule for all personal names: the pronunciation the person uses for themselves is the correct one, and asking is polite rather than awkward. The names guide makes the wider version of this argument.

Irish surnames are built from two elements. Ó means descendant of and Mac means son of. Anglicised, Ó became the O' of O'Brien, O'Sullivan and O'Neill, and Mac became Mc or Mac. The apostrophe in O'Brien is not a contraction of anything — it is a printer's substitute for the fada.

The same rules from sections 3 to 5 apply inside surnames. Ó Súilleabháin, the original of O'Sullivan, has the bh you already know. Mac Cárthaigh gives McCarthy. Once you can read the given names, the surnames come free.

Irish English itself — the accent, as distinct from the language — has its own pronunciation features, including the dental t and d that stand in for th. Set the accent to Irish on the main screen to hear these names read by an Irish voice rather than an English one.

Read slowly first. Pronounce each syllable deliberately before trying to blend them at full speed. Rushing hides the vowel and consonant shapes your ear needs to learn.

Record yourself. Most phones have a voice memo app — record a word, then compare it to the playback here. Hearing the gap between your version and the model accent makes targeted practice far easier.

Focus on one accent. Jumping between American, British and Australian in the same session creates confusion. Pick the accent you encounter most and stick with it until the patterns feel natural.

Every word above is a button. Set the accent and voice you want on the main screen, then come back — the guides use whatever you chose. To hear two accents against each other, use Compare; to test whether you can actually hear a contrast, use the listening quiz.
