The Irish Language Grimoire — Prepositional Pronouns
Irish prepositions fuse with the pronouns that follow them into single words. “At me” is not “ag mé”; it is “agam”. “On you” is not “ar tú”; it is “ort”. Each preposition has its own paradigm of seven fused forms (one for each person). These prepositional pronouns are also where Irish locates the construction for possession: “I have a dog” is “Tá madra agam” — literally “A dog is at-me”. They are unavoidable in everyday speech.
The basic frame
Eleven high-frequency prepositions take fused pronominal forms. Here are the most important ones with their full paradigms:
| Preposition | + mé (I) | + tú (you sg) | + sé (he) | + sí (she) | + muid (we) | + sibh (you pl) | + siad (they) |
|---|---|---|---|---|---|---|---|
| ag (at) | agam | agat | aige | aici | againn | agaibh | acu |
| ar (on) | orm | ort | air | uirthi | orainn | oraibh | orthu |
| as (out of) | asam | asat | as | aisti | asainn | asaibh | astu |
| de (from) | díom | díot | de | di | dínn | díbh | díobh |
| do (to / for) | dom | duit | dó | di | dúinn | daoibh | dóibh |
| faoi (under / about) | fúm | fút | faoi | fúithi | fúinn | fúibh | fúthu |
| i (in) | ionam | ionat | ann | inti | ionainn | ionaibh | iontu |
| le (with) | liom | leat | leis | léi | linn | libh | leo |
| ó (from) | uaim | uait | uaidh | uaithi | uainn | uaibh | uathu |
| roimh (before) | romham | romhat | roimhe | roimpi | romhainn | romhaibh | rompu |
| trí (through) | tríom | tríot | tríd | tríthi | trínn | tríbh | tríothu |
These are not optional. Ag mé and ar tú are simply ungrammatical in standard Irish.
Why this matters: possession
Irish has no verb “to have”. Possession is expressed by saying that something IS at someone. The construction is:
Tá + [thing] + ag + [person]
When “person” is a pronoun, it fuses with ag:
| English | Irish | Literal |
|---|---|---|
| I have a dog. | Tá madra agam. | A-dog is at-me. |
| You have a book. | Tá leabhar agat. | A-book is at-you. |
| She has time. | Tá am aici. | Time is at-her. |
| We have a house. | Tá teach againn. | A-house is at-us. |
| They have children. | Tá páistí acu. | Children are at-them. |
This is the single most important pattern in everyday Irish. Almost every “to have” sentence in English maps to this Tá X agam/agat/… structure.
When “person” is a named noun, the unfused preposition is used:
- Tá madra ag Máire. — Mary has a dog.
Why this matters: emotion and condition
Irish frequently expresses emotion as something that is “on” the person, using the preposition ar and its fused pronouns:
| English | Irish | Literal |
|---|---|---|
| I am sad. | Tá brón orm. | Sadness is on-me. |
| He is angry. | Tá fearg air. | Anger is on-him. |
| She is afraid. | Tá eagla uirthi. | Fear is on-her. |
| We are tired. | Tá tuirse orainn. | Tiredness is on-us. |
| They are hungry. | Tá ocras orthu. | Hunger is on-them. |
The emotion is named as a noun, not an adjective. The construction places the emotion “on” the person, and the person appears as the fused preposition.
This is sometimes called the “on-me” construction. It pairs with the “at-me” possession construction to cover most of what English does with adjectives and “have”.
Other common uses
Beyond possession and emotion, prepositional pronouns appear constantly:
- Tabhair dom é. — Give it to me.
- Tar liom. — Come with me.
- Bain as! — Get out of (it)! (as = out-of-it)
- Bhí mé ag caint leis. — I was talking to him.
- Tá súil agam. — I hope. (Literally: “hope is at-me”)
Many idiomatic Irish expressions are built on prepositional pronouns, and learning them produces large fluency gains.
Emphatic forms
Each fused pronoun has an emphatic counterpart, made by adding -sa, -se, -san, -ne, -(s)e depending on the form:
- agam → agamsa (at me, emphatic)
- ort → ortsa (on you, emphatic)
- againn → againne (at us, emphatic)
The emphatic is used for contrast: Tá leabhar agamsa, ach níl ceann agatsa — I have a book, but you do not.
