Irish or Gaelic? The language and its dialects
Last updated 27 October 2026
Irish, Gaelic, Irish Gaelic, Gaeilge: they're all the same language. In Ireland it's called Irish. Here's why the names differ, how Irish relates to Scottish Gaelic, and what the three dialects are.
Irish, Gaelic or Gaeilge?
In Ireland, the language is called Irish in English and Gaeilge in Irish. The Constitution calls it the first official language of the State. Outside Ireland, especially in North America, people often say Irish Gaelic or Gaelic, partly to avoid confusion with Irish English. Nobody will mind which you use, but in Ireland "Gaelic" on its own usually means Gaelic football.
Irish and Scottish Gaelic
Irish, Scottish Gaelic (Gàidhlig) and Manx (Gaelg) all come from the Goidelic branch of the Celtic languages. Gaelic spread from Ireland to Scotland and the Isle of Man in the early Middle Ages, and the three grew apart over the centuries. They share a lot of vocabulary, and Ulster Irish is closest to Scottish Gaelic, but they are separate languages with different spelling and pronunciation. If you want to learn the language of Ireland, learn Irish.
The three dialects
Irish is spoken as a community language in the Gaeltacht, the Irish-speaking areas mostly along the west coast. Each region has its own dialect, with differences in pronunciation, some words and some grammar. They're like accents in English: speakers of all three understand each other.
Munster Irish
Kerry (Corca Dhuibhne, Uíbh Ráthach), west Cork (Cúil Aodha, Cléire) and Waterford (An Rinn)
"How are you?" Conas atá tú? · "Irish" Gaelainn
Connacht Irish
Galway (Conamara, Árainn) and Mayo (Iorras, Tuar Mhic Éadaigh)
"How are you?" Cén chaoi a bhfuil tú? · "Irish" Gaeilge
Ulster Irish
Donegal (Gaoth Dobhair, Rann na Feirste, Gleann Cholm Cille, Toraigh)
"How are you?" Cad é mar atá tú? · "Irish" Gaeilic
The Meath Gaeltacht, at Ráth Cairn and Baile Ghib, was settled in the 1930s by families from the western Gaeltacht, most of them from Conamara.
Some differences you'll hear
- Stress. Munster Irish often stresses a long vowel later in the word, so cailín (girl) sounds like "ka-LEEN"; Connacht and Ulster say "KA-leen".
- Verbs. Munster keeps more personal endings: bhíos where others say bhí mé (I was).
- Negatives. Ulster Irish often uses cha for "not": cha bhfuil alongside the standard níl (is not).
An Caighdeán: Standard Irish
An Caighdeán Oifigiúil, the Official Standard, was first published in 1958 to give Irish one written form for schools, government and publishing. It's the Irish of textbooks, exams, road signs and dictionaries. It isn't a dialect anyone grew up with: people write the standard and speak their own dialect.
That's why learning the standard with an ear for one dialect is the usual route. Dúisigh teaches Standard Irish and notes how Munster, Connacht and Ulster say things differently, so you'll understand Irish wherever you hear it.
Irish today
In the 2022 census about 1.87 million people in the Republic said they could speak Irish, and about 72,000 spoke it every day outside school. Irish has been an official language of the European Union since 2007, with full status since 2022, and it was given official recognition in Northern Ireland in 2022. There's Irish-language TV (TG4), national radio (Raidió na Gaeltachta), a growing number of Gaelscoileanna, and more learners than ever.
Common questions
Is it called Irish or Gaelic?
In Ireland it's called Irish in English and Gaeilge in Irish. Outside Ireland, especially in the US, people often say Irish Gaelic or just Gaelic. All mean the same language. In Ireland, "Gaelic" more often means the GAA sports: Gaelic football.
Is Irish Gaelic the same as Scottish Gaelic?
No. Irish (Gaeilge), Scottish Gaelic (Gàidhlig) and Manx (Gaelg) are three related languages from the same Goidelic branch. They share a lot of vocabulary, and Ulster Irish and Scottish Gaelic are partly understandable to each other, but spelling, pronunciation and grammar differ.
How do you pronounce Gaeilge?
Roughly "GAYL-gyeh" in Connacht. In Munster it's Gaelainn ("GAY-lin") and in Ulster Gaeilic ("GAY-lik").
Which Irish dialect should I learn?
Learn Standard Irish (An Caighdeán Oifigiúil), the written standard used in schools, with an ear for one dialect: the one where you have family, holiday or will meet speakers. Speakers of all three dialects understand each other.
How many people speak Irish?
In the 2022 census about 1.87 million people in the Republic of Ireland said they could speak Irish, and about 72,000 spoke it daily outside the education system. Irish is the first official language of Ireland and an official language of the European Union.
