Irish Grammar

Personal pronouns: mé (I), tú (you), sé (he), sí (she), muid/sinn (we), sibh (you pl.), siad (they). Emphatic forms add suffixes: mise, tusa, seisean, etc.

Lenition adds 'h' after the initial consonant: b→bh, c→ch, d→dh, f→fh (silent), g→gh, m→mh, p→ph, s→sh, t→th. Triggered by many common constructions including past tense, feminine nouns after 'an', and possessives.

Eclipsis prefixes a voiced consonant: b→mb, c→gc, d→nd, f→bhf, g→ng, p→bp, t→dt. Vowels get 'n-' prefix. Triggered by: 'i' + place, plural article 'na', preposition 'ar' in some forms, and numbers 7-10.

Irish has one article 'an' (singular) and 'na' (plural/genitive). No indefinite article exists. The article triggers mutations: lenition of feminine singular nominative, eclipsis in genitive plural, 't-' before masculine vowels.

Irish nouns are masculine or feminine. Gender affects article behavior, adjective agreement, and pronoun reference. Most nouns ending in a broad consonant are masculine; those ending in a slender consonant, -óg, or -eog tend to be feminine.

The substantive verb 'bí' in present tense: tá mé, tá tú, tá sé/sí, táimid, tá sibh, tá siad. Negative: níl. Question: an bhfuil? Used for states, locations, and progressive actions.

The copula 'is' identifies or classifies: Is múinteoir mé (I am a teacher). Different from 'tá' which describes states. Negative: ní. Question: an. Past/conditional: ba/b'.

Irish has no words for 'yes' or 'no' - answers repeat the verb. Negative particles: ní/níl (present), níor (past) cause lenition. Question particles: an/ar cause eclipsis or lenition respectively.

Adjectives follow the noun and agree in gender, number, and case. Feminine singular nouns cause lenition of the adjective. Plural adjectives take various endings (-a, -e).

Common prepositions: ag (at), ar (on), as (out of), de (of/from), do (to/for), faoi (under/about), i (in/into), le (with), ó (from), roimh (before), thar (over), trí (through).

Prepositions combine with pronouns into single words: ag → agam, agat, aige, aici, againn, agaibh, acu. Essential for common expressions like 'Tá... agam' (I have).

Cardinal numbers 1-100. Numbers 2-6 cause lenition, 7-10 cause eclipsis. Special counting forms exist. 'Aon' (one) lenites, 'dhá' (two) lenites and noun is singular.

Telling time (Tá sé a... a chlog), days of the week (Dé Luain, Dé Máirt...), months (Eanáir, Feabhra...), and basic temporal expressions (inniu, amárach, inné).

Present habitual tense of regular verbs (1st conjugation: -ann, 2nd conjugation: -aíonn/-íonn). Used for habitual actions: Ólann sé tae (He drinks tea). Distinct from progressive 'tá + ag'.

Essential phrases: greetings (Dia duit, Conas atá tú?), introductions (... is ainm dom), politeness (le do thoil, go raibh maith agat), and conversational basics.

Possession expressed with 'ag' (Tá... agam = I have) and possessive adjectives: mo (my, +lenition), do (your, +lenition), a (his, +lenition / her, +h before vowels), ár (our, +eclipsis).

The progressive (continuous) aspect uses 'tá + ag + verbal noun': Tá mé ag léamh (I am reading). The verbal noun is the Irish equivalent of an infinitive/gerund. Distinct from habitual present.

Question words: cad/céard (what), cé (who), cá/cén áit (where), cathain (when), conas (how), cén fáth (why), cé mhéad (how much/many). Each has different mutation effects.

Expressing ability, obligation, and desire: 'is féidir le' (can), 'caithfidh' (must), 'ba mhaith le' (would like), 'ní mór do' (must/need to). Uses prepositional pronouns.

Weather: 'Tá sé' + adjective (Tá sé fuar = It's cold). Feelings use 'ar' + person: Tá áthas orm (I'm happy), Tá eagla orm (I'm afraid). Both are essential idiomatic patterns.

The broad/slender rule 'caol le caol agus leathan le leathan' (slender with slender and broad with broad): vowels on both sides of a consonant must agree. This governs spelling and pronunciation throughout Irish.

Colour adjectives showing gender mutation: dearg (red), gorm (blue), glas (green), dubh (black), bán (white). Feminine nouns cause lenition: bean bhán (a fair woman).

Prepositions combine with the article to form special forms: i + an = sa/san, de + an = den, do + an = don, le + an = leis an, ag + an = ag an. Each triggers specific mutations.

Basic 'if' sentences using 'má' (if, +lenition) with present tense and 'mura' (if not, +eclipsis). Open conditions for real possibilities: Má tá tú sásta (If you are satisfied).

Future tense: 1st conjugation adds -faidh/-fidh, 2nd conjugation adds -óidh/-eoidh. Irregular verbs have unique future stems. Negative: ní + lenition. Question: an + eclipsis.

Conditional: adds -fadh/-feadh (1st conj.) or -ódh/-eodh (2nd conj.) + lenition. Used for 'would' and in conditional sentences with 'dá' (if). Irregular verbs have special forms.

Habitual past for repeated actions: lenition + -adh/-eadh (1st conj.) or -aíodh/-íodh (2nd conj.). 'Bhíodh' for 'used to be'. Distinct from the simple past.

Irish retains an active genitive case for possession and after verbal nouns. Nouns change form: broadening/slenderization, suffix changes. Triggers lenition of following adjectives.

Comparative uses 'níos' + comparative form: níos mó (bigger), níos fearr (better). Superlative uses 'is' + comparative: is mó (biggest). Past uses 'ní ba/b''. Many irregular forms.

Time clauses: nuair a (when), sula (before, +eclipsis), tar éis (after), fad a (while), go dtí go (until). Different particles trigger different mutations in the dependent clause.

Past/conditional copula 'ba/b'' + lenition: ba mhaith liom (I would like), b'fhéidir (maybe), ba é (it was). Negative: níor/níorbh. Question: ar/arbh. Distinct tense forms.

First conditional with 'má' (if, +lenition for present/past): Má thagann sé, beidh mé sásta. Open conditions use present or future. 'Mura' (if not) + eclipsis for negative conditions.

When a verbal noun takes an object, the object goes in the genitive and comes between 'ag' and the verbal noun: ag léamh an leabhair (reading the book). Pronouns use 'á' + lenition/eclipsis.

Expressing purpose: chun/le (to/in order to) + verbal noun. Result: chomh...go (so...that). Also 'ar mhaithe le' (for the sake of), 'i dtreo go' (so that).

Frequently used idiomatic patterns: 'tá + noun + ag + person' (emotions/states), 'bain úsáid as' (use), 'cuir ceist ar' (ask), 'tóg go bog é' (take it easy). Prepositional patterns unique to Irish.

Indirect relative clauses use 'a' + eclipsis and a resumptive prepositional pronoun: an fear a bhfuil a mhac tinn (the man whose son is sick). More complex than direct relatives.

Extended passive using autonomous forms across all tenses and moods. Causative constructions with 'cuir' and 'tabhair ar': Chuir sé orm é a dhéanamh (He made me do it).

Cause: mar (because), toisc go (because), ós rud é go (since). Purpose: chun/le go (so that), d'fhonn (in order to). Concessive: cé go (although), bíodh go (even though).

Abstract nouns formed from adjectives (-acht/-eacht: maith→maitheacht) and verbs (-ú/-iú: forbairt→forbairt). Used in formal and academic discourse for expressing complex ideas.

The subjunctive (past subjunctive) used after 'dá' (if), 'go' (that...may), and in wishes: Go raibh maith agat (May you have good). Forms: present subjunctive nearly extinct; past subjunctive still common.

Advanced connectors for arguments: mar sin féin (nevertheless), dá bhrí sin (therefore), ina theannta sin (in addition), ar an lámh eile (on the other hand), go háirithe (especially).

Synthetic (combined person+verb) forms used in formal/literary Irish: léimid (we read) vs. léann muid. Past subjunctive, literary imperative forms, and archaic tenses found in literature.

Understanding how Irish speakers shift between registers: formal written Gaeilge, standard spoken, and heavily English-influenced 'Béarlachas'. Recognizing and avoiding anglicisms.

Two-word prepositions requiring genitive: ar feadh (for the duration of), i rith (during), de bharr (because of), in aice le (near), os comhair (in front of), i ndiaidh (after).

Advanced literary syntax: fronting for emphasis (Is é Seán a rinne é), cleft constructions, inverted word order for stylistic effect, and the use of 'is amhlaidh' (it is the case that).

Key differences between Munster, Connacht, and Ulster Irish: pronunciation, vocabulary (coicís/coicthíos), verb forms (Munster synthetic vs analytic), and the dative case (Munster only).

Understanding older Irish literary forms: Classical Irish (13th-17th century) spelling and grammar conventions, Early Modern Irish verb forms, and archaic constructions found in proverbs and poetry.

Advanced stylistic devices: topicalization, rhetorical questions, litotes, deliberate use of long vs short forms for emphasis. Awareness of register shifting and audience-appropriate language.
