Irish (Gaeilge)

1. Introduction & endangerment status

Irish (Gaeilge), sometimes called Irish Gaelic, is an Insular Celtic language of the Goidelic branch, alongside Scottish Gaelic and Manx. It is the national and first official language of the Republic of Ireland and an official language of the European Union, yet its everyday community use is concentrated in the Gaeltacht — designated Irish-speaking districts mainly along the western seaboard (Donegal, Connemara/Galway, Kerry and others).¹² Confidence: High.

The 2022 census recorded about 1.87 million people in the Republic with some ability in Irish, but everyday use is far smaller: roughly 65,000 Irish speakers live in the Gaeltacht, of whom about 20,000 speak it daily outside the education system. UNESCO's Atlas of the World's Languages in Danger classified Irish as 'definitely endangered' — meaning children are largely no longer acquiring it as a first language in the home — though commentators note state support has since strengthened.²³ Confidence: High.

Despite its endangerment in daily use, Irish has exceptional institutional support: constitutional status, a place in the school curriculum, the Gaelscoileanna (Irish-medium schools), the television service TG4 and radio's RTÉ Raidió na Gaeltachta, and EU working-language status. A 20-Year Strategy for the Irish Language (2010–2030) coordinates revival. This makes Irish one of the most resourced of all endangered languages for the learner.²³ Confidence: High.

This guide rises through the eight CEFR sub-levels, from the alphabet (A1.1) toward reading Irish media and literature and joining the language community (B2.2). Each level is marked with a visible heading.

Irish is written in the Latin alphabet, traditionally using 18 letters; j, k, q, v, w, x, y and z appear mainly in loanwords. A síneadh fada (long accent) over a vowel — á, é, í, ó, ú — marks length and changes meaning (e.g. Seán). The crucial principle is the broad/slender distinction: every consonant is either 'broad' (next to a, o, u) or 'slender' (next to e, i), which changes its pronunciation, captured by the spelling rule caol le caol, leathan le leathan ('slender with slender, broad with broad').¹ Confidence: High.

A first set of greetings and polite expressions opens almost any conversation with a fellow learner or community member. All forms below are drawn from the cited reference materials.¹

The cardinal numerals one to ten are listed below, with twenty and one hundred. Like the other Celtic languages, the traditional higher numbers use a vigesimal (base-twenty) system.⁴

Irish default word order is verb–subject–object (VSO): Itheann an cat 'The cat eats' (literally 'eats the cat'). There is no indefinite article, and the definite article is an (singular) / na (plural). Nouns have two grammatical genders (masculine and feminine) and a case system whose effects are seen mainly through initial mutations and the article.¹² Confidence: High.

A starter set of everyday words — family, common nouns and colours — for first sentences:

The signature Celtic feature is initial mutation: the first sound of a word changes with grammar. Irish has two — lenition (séimhiú), shown by adding h (bád 'boat' → mo bhád 'my boat'), and eclipsis (urú), where one consonant is written before another and replaces its sound (bád → ár mbád 'our boat', pronounced 'mád'). Knowing when each is triggered is the central intermediate task.¹² Confidence: High.

Irish verbs conjugate for tense and (partly) person, and the verb 'to be' has two distinct forms: the substantive verb bí (tá / níl …) for states and actions, and the copula is for identity and classification — a famous difficulty for learners. Possession is expressed not with a verb 'to have' but with the preposition ag 'at': tá leabhar agam = 'I have a book' (literally 'is a book at-me'). Irish keeps separate singular tú and plural sibh for 'you'.¹² Confidence: High.

Advanced competence means handling the three great dialects — Ulster (Donegal), Connacht (Galway/Mayo) and Munster (Kerry/Cork) — which differ in pronunciation, vocabulary and even some grammar, plus the standardised written form An Caighdeán Oifigiúil. Long contact with English has produced loanwords and the distinctive English of Ireland (Hiberno-English) in return; recognising borrowed material helps keep the inherited Goidelic structure clear.¹² Confidence: High.

At the top of the ladder the living community is the classroom. Irish has the television channel TG4, RTÉ Raidió na Gaeltachta, a continuous literary tradition stretching from medieval manuscripts and the bardic schools to a vibrant modern literature (Máirtín Ó Cadhain, Nuala Ní Dhomhnaill and others), and rich online resources such as the dictionary teanglann.ie and foclóir.ie. Reading goals at this level include Irish news, fiction and poetry.¹² Confidence: High.

Revitalization & preservation

Irish enjoys strong legal and educational backing: constitutional first-official-language status, a place on every school curriculum, the growing Gaelscoil (Irish-medium school) movement, the TG4 television service, RTÉ Raidió na Gaeltachta, official EU language status (since 2007/2022), and the 20-Year Strategy for the Irish Language 2010–2030. The continuing challenge, reflected in UNESCO's 'definitely endangered' label, is converting widespread school-acquired ability into daily home and community use, especially within the shrinking Gaeltacht.²³

Each row carries the target word, English translation, an example sentence and its translation where one is given, an (empty) audio placeholder, notes, and a category for beginner-first review. Only items that could be reliably sourced are included; no vocabulary has been invented. The dataset is eligible for additive expansion toward the 100-word target in future runs.
