Compound Tenses in Irish

Overview

Irish uses compound tense constructions to express perfect, pluperfect, and "about to" aspects that the simple tenses cannot capture. These are formed by combining tá (or bhí for past) with prepositional phrases and verbal nouns, creating precise aspectual distinctions.

The most important compound tense is the perfect, formed with tá + tar éis + verbal noun: Tá mé tar éis an leabhar a léamh (I have just read the book). The pluperfect uses bhí instead: Bhí sé tar éis dul abhaile (He had just gone home). Another construction, tá + i ndiaidh, is sometimes used interchangeably with tar éis in certain dialects.

A related construction, tá + ar tí (about to), expresses imminent actions: Bhí mé ar tí dul amach (I was about to go out). These compound tenses fill gaps in the Irish tense system and add important temporal and aspectual nuances to your expression.

How It Works

Perfect: tá + tar éis + VN

Irish	English	Time reference
Tá mé tar éis é a léamh.	I have just read it.	Recent past
Tá sí tar éis teacht.	She has just arrived.	Recent past
Tá siad tar éis imeacht.	They have just left.	Recent past

Pluperfect: bhí + tar éis + VN

Irish	English	Time reference
Bhí sé tar éis dul abhaile.	He had just gone home.	Past before past
Bhí mé tar éis an obair a chríochnú.	I had just finished the work.	Past before past

About to: tá + ar tí + VN

Irish	English
Tá mé ar tí dul amach.	I am about to go out.
Bhí mé ar tí é a rá.	I was about to say it.
Tá sé ar tí tosú.	It is about to start.

Alternative: tá + i ndiaidh + VN

Irish	English	Note
Tá mé i ndiaidh teacht.	I have just come.	Connacht preference
Tá sí i ndiaidh dul abhaile.	She has just gone home.	Same meaning as tar éis

With Objects

When the compound tense includes an object, the object goes between the verbal noun and tar éis using the genitive or the a + verbal noun pattern:

Irish	English
Tá mé tar éis an leabhar a léamh.	I have just read the book.
Tá sé tar éis an dinnéar a ithe.	He has just eaten the dinner.

Examples in Context

Common Mistakes

Confusing "tar éis" with the simple past

• Wrong: Using D'ith mé when you mean "I have just eaten"
• Right: Tá mé tar éis ithe.
• Why: The simple past (D'ith mé) simply states "I ate." The perfect (Tá mé tar éis ithe) emphasizes the recent completion of the action.

Wrong word order with objects

• Wrong: Tá mé tar éis léamh an leabhar
• Right: Tá mé tar éis an leabhar a léamh.
• Why: The object comes between tar éis and the verbal noun, connected by the particle a.

Confusing "ar tí" with "tar éis"

• Wrong: Tá mé ar tí an leabhar a léamh when meaning "I have just read the book"
• Right: Tá mé tar éis an leabhar a léamh.
• Why: Ar tí means "about to" (future orientation), while tar éis means "just after" (past orientation).

Usage Notes

The choice between tar éis and i ndiaidh is largely dialectal. Tar éis is standard and used everywhere, while i ndiaidh is particularly common in Connacht Irish. Both constructions are correct and interchangeable in meaning. The word díreach (just/exactly) is often added for emphasis: Tá mé díreach tar éis teacht (I have just this moment arrived).

Practice Tips

1. Describe five things you have just done using Tá mé tar éis...: arriving, eating, reading, calling someone, finishing work.
2. Practice the pluperfect by narrating a sequence of past events: Bhí mé tar éis an dinnéar a ithe nuair a tháinig sé (I had just eaten dinner when he arrived).
