Prepositional Pronouns in Irish

Overview

Prepositional pronouns are one of the most distinctive features of Irish grammar. When a preposition meets a personal pronoun, they fuse into a single word. English says "at me," but Irish says agam — one word combining the preposition ag (at) with mé (me). This happens with every simple preposition and every pronoun, creating a rich system of forms.

At the A1 level, prepositional pronouns are essential because they appear in some of the most common expressions in the language. "I have" is expressed as "Tá ... agam" (literally, "there is ... at me"). "I am sorry" is "Tá brón orm" (sadness is on me). "I like" is "Is maith liom" (it is good with me). You simply cannot speak Irish without these forms.

Each preposition has a full set of pronoun forms — seven for each — so there are many forms to learn. The good news is that patterns repeat across prepositions, and the most common ones (ag, ar, le, do) will carry you through most conversations.

How It Works

The preposition "ag" (at) — used for possession

Person	Form	English
1st sg.	agam	at me (I have)
2nd sg.	agat	at you (you have)
3rd sg. m.	aige	at him (he has)
3rd sg. f.	aici	at her (she has)
1st pl.	againn	at us (we have)
2nd pl.	agaibh	at you all (you have)
3rd pl.	acu	at them (they have)

The preposition "ar" (on) — used for feelings/states

Person	Form	English
1st sg.	orm	on me
2nd sg.	ort	on you
3rd sg. m.	air	on him
3rd sg. f.	uirthi	on her
1st pl.	orainn	on us
2nd pl.	oraibh	on you all
3rd pl.	orthu	on them

The preposition "le" (with) — used for likes/opinions

Person	Form	English
1st sg.	liom	with me
2nd sg.	leat	with you
3rd sg. m.	leis	with him
3rd sg. f.	léi	with her
1st pl.	linn	with us
2nd pl.	libh	with you all
3rd pl.	leo	with them

Common Mistakes

Separating the preposition and pronoun

• Wrong: Tá leabhar ag mé
• Right: Tá leabhar agam
• Why: In Irish, the preposition and pronoun must be combined into a single word. They are never used separately.

Mixing up similar-sounding forms

• Wrong: Tá brón agam (meaning "I have sadness" — unidiomatic)
• Right: Tá brón orm (sadness is on me)
• Why: Different prepositions express different relationships. Feelings use ar (on), not ag (at). Learn which preposition goes with which expression.

Forgetting the feminine third-person forms

• Wrong: Tá a fhios aige (referring to a woman)
• Right: Tá a fhios aici
• Why: The third-person forms differ by gender. Aige is masculine (at him), aici is feminine (at her).

Practice Tips

1. Start with the ag forms since they express possession — the most frequent construction. Drill "Tá ___ agam/agat/aige/aici/againn/agaibh/acu" until it is automatic.
2. Learn common expressions as fixed phrases: "Tá ocras orm" (I'm hungry), "Tá brón orm" (I'm sorry), "Is maith liom" (I like). The expressions will teach you the prepositional pronouns naturally.
3. Make a grid of the three most common prepositions (ag, ar, le) with all seven person forms and review it daily.
