Compound Tenses in Irish

In Brief

Irish commonly expresses a recently completed action with bí + subject + tar éis or i ndiaidh + verbal noun: Tá mé tar éis an leabhar a léamh means “I have just read the book.” Change tá to bhí to move the viewpoint into the past, and use ar tí + verbal noun for an action that is about to happen: Bhí mé ar tí imeacht means “I was about to leave.”

Overview

Irish does not have to copy the English pattern have + past participle to talk about a completed action. Instead, it can combine a form of bí (“be”) with a phrase meaning “after” and a verbal noun (a verb form used in many constructions where English uses “doing” or “to do”). The result is sometimes called the Irish “after-perfect”: Tá sí tar éis teacht is literally shaped rather like “She is after coming,” but naturally means “She has just come” or “She has arrived.”

These forms add aspect—the speaker’s view of whether an event is completed, ongoing, imminent, or relevant at a particular time. Compare Léigh mé an leabhar (“I read the book”) with Tá mé tar éis an leabhar a léamh (“I have just read the book”). The first simply reports a past event. The second looks back from the present and presents its completion as recent or currently relevant.

At B2, the goal is not merely to memorise tar éis. You should be able to move the viewpoint between present and past, form questions and negatives, place objects correctly, and avoid translating every English perfect tense word for word. English uses its present perfect very broadly; the Irish after-perfect is more strongly associated with recent completion or a resulting state.

How It Works

The central pattern

The basic construction has four parts:

Part	Function	Example
form of bí	places the viewpoint in time	tá, bhí, beidh
subject	says who performs the action	mé, sí, na páistí
aspect phrase	marks completion or imminence	tar éis, i ndiaidh, ar tí
verbal-noun phrase	names the action	teacht, an obair a chríochnú

The most useful patterns are:

Meaning	Irish pattern	Model
has/have just done	tá + subject + tar éis + verbal noun	Tá Seán tar éis imeacht.
had just done	bhí + subject + tar éis + verbal noun	Bhí Seán tar éis imeacht.
has/have just done, close alternative	tá + subject + i ndiaidh + verbal noun	Tá Seán i ndiaidh imeacht.
had just done, close alternative	bhí + subject + i ndiaidh + verbal noun	Bhí Seán i ndiaidh imeacht.
is/am/are about to do	tá + subject + ar tí + verbal noun	Tá Seán ar tí imeacht.
was/were about to do	bhí + subject + ar tí + verbal noun	Bhí Seán ar tí imeacht.

The verbal noun itself does not change for person. The subject appears after the form of bí: tá mé, tá tú, tá sí, táimid or tá muid, tá sibh, tá siad. In the past, use the appropriate form of bí, normally bhí: bhí mé, bhí siad.

Present viewpoint: recent completion

Use present bí when the completed event is viewed from now:

• Tá mé tar éis ithe. — “I have just eaten.”
• Tá an bus tar éis imeacht. — “The bus has just left.”
• Tá siad i ndiaidh teacht. — “They have just arrived.”

Both tar éis and i ndiaidh literally involve the idea of being “after” an event. In this construction they generally mark completed action, not an action still in progress. Although descriptions of Irish grammar may group them under broader compound or aspectual forms, do not interpret Tá siad i ndiaidh teacht as “They are arriving continuously.”

Past viewpoint: completion before another past point

Replace tá with bhí when the reference point is in the past:

• Bhí sé tar éis dul abhaile. — “He had just gone home.”
• Bhíomar tar éis dinnéar a ithe nuair a ghlaoigh sí. — “We had eaten dinner when she called.”

This often corresponds to the English pluperfect or past perfect (a form such as “had left,” which places one event before another past event). The second past event may be stated, introduced by nuair (“when”), or simply understood from the conversation.

The after-perfect can imply “had just,” but context controls how recent the first event feels. Add an explicit time phrase if precision matters.

Objects with the verbal noun

With a noun object, a frequent pattern is:

object + a + verbal noun

• an leabhar a léamh — “to read the book”
• an obair a chríochnú — “to finish the work”
• an doras a dhúnadh — “to close the door”

That gives Tá mé tar éis an obair a chríochnú. The particle a links the object to the verbal noun. Its effect on the following word follows the usual rules: it often causes lenition (a spelling change such as dúnadh → dhúnadh), while vowel-initial forms show no added letter here: é a ól.

Pronoun objects also come before a + verbal noun:

• é a léamh — “to read it” (masculine object)
• í a fheiceáil — “to see her/it” (feminine object)
• iad a cheannach — “to buy them”

Therefore: Tá mé tar éis é a léamh, not a word-for-word copy of English “read it” order.

Some verbal-noun constructions have their own object patterns, so vocabulary should be learned as a phrase rather than by assuming that every verb behaves identically. The models above are the central patterns for this topic.

Questions and negatives

Because bí carries the tense, questions and negatives are formed on bí, not on the main action:

Type	Present	Past
statement	Tá sí tar éis teacht.	Bhí sí tar éis teacht.
negative	Níl sí tar éis teacht.	Ní raibh sí tar éis teacht.
question	An bhfuil sí tar éis teacht?	An raibh sí tar éis teacht?

The same applies to i ndiaidh and ar tí:

• An bhfuil tú ar tí imeacht? — “Are you about to leave?”
• Ní raibh mé ar tí é sin a rá. — “I was not about to say that.”
• Níl siad i ndiaidh freagra a thabhairt fós. — “They have not given an answer yet.”

A different direction: ar tí

The phrase ar tí presents an event as imminent—on the point of happening. Unlike tar éis and i ndiaidh, it looks forward from the reference point:

View from now	View from a past moment
Tá an traein ar tí imeacht. — The train is about to leave.	Bhí an traein ar tí imeacht. — The train was about to leave.

Bhí ... ar tí does not say whether the event eventually happened. Bhí mé ar tí glaoch ort nuair a tháinig tú isteach means that the call was imminent when something else happened; the context may suggest that it was interrupted.

Common Mistakes

Translating every English “have” perfect with tar éis

• Wrong: Tá mé tar éis cuairt a thabhairt ar Éirinn trí huaire when you only mean general life experience.
• Better: Thug mé cuairt ar Éirinn trí huaire.
• Why: English “I have visited Ireland three times” does not necessarily mean “just now.” The Irish simple past plus trí huaire naturally reports the completed experiences. Reserve the after-perfect for a genuinely recent completion or a result viewed from the reference point.

Conjugating the main action as a past-tense verb

• Wrong: Tá mé tar éis léigh mé an leabhar.
• Right: Tá mé tar éis an leabhar a léamh.
• Why: After tar éis, use a verbal-noun phrase. Tense is carried by tá, not by a second finite verb (a verb marked for tense and able to head its own clause).

Putting the object after the verbal noun

• Wrong: Tá mé tar éis léamh an leabhar.
• Right: Tá mé tar éis an leabhar a léamh.
• Why: In the standard object pattern taught here, the object comes before a + verbal noun.

Using tá for a past viewpoint

• Wrong: Tá sé tar éis imeacht nuair a tháinig mé for “He had left when I arrived.”
• Right: Bhí sé tar éis imeacht nuair a tháinig mé.
• Why: The viewpoint is the past moment when you arrived, so bí must also be past: bhí.

Confusing “after” with “about to”

• Wrong: Tá an scannán tar éis tosú for “The film is about to start.”
• Right: Tá an scannán ar tí tosú.
• Why: tar éis looks back at a completed start; ar tí looks forward to an imminent one. Tá an scannán tar éis tosú means that the film has already started.

Building the negative on the verbal noun

• Wrong: Tá sí ní tar éis teacht.
• Right: Níl sí tar éis teacht.
• Why: Negate the form of bí: tá → níl and bhí → ní raibh.

Usage Notes

The English translation “have just” is a useful learning shortcut, not a rigid formula. Depending on context, Tá sé tar éis imeacht may be translated as “He has just left,” “He has left,” or “He is gone.” The Irish construction highlights completed action and its relation to now; an English translator chooses the most natural wording.

Tar éis and i ndiaidh overlap strongly in the after-perfect. Choice varies with speaker, region, and style, so learners should recognise both rather than treating one as incorrect. For dependable active use, choose one model consistently at first, then notice what speakers around you prefer.

Do not confuse the aspectual construction with ordinary time phrases. Tar éis an chruinnithe means “after the meeting,” where a noun follows. In Táimid tar éis an cruinniú a chríochnú, the phrase participates in the after-perfect and is followed by the complete verbal-noun phrase “to finish the meeting.” Likewise, i ndiaidh an dinnéir can simply mean “after dinner.”

In informal English, especially in varieties historically influenced by Irish, you may hear “I’m after doing it.” That resemblance can help you remember the Irish structure, but standard English usually translates it with “have just done,” not literally with “am after doing.”

Beyond the Basics: Wider Time Frames and Subtle Contrasts

The form of bí can move the viewpoint beyond present and past. A future form can describe completion before a future reference point:

• Beidh mé tar éis an obair a chríochnú faoin Aoine. — “I will have finished the work by Friday.”

Here faoin Aoine (“by Friday”) supplies the future deadline. This is the same underlying logic: at that future point, the speaker expects to be “after” completing the work.

The simple past and the after-perfect can describe the same real-world event but organise the information differently:

Irish	Natural English	Focus
D’imigh sí ar a hocht.	She left at eight.	the past event and its time
Tá sí tar éis imeacht.	She has just left.	completion viewed from now
Bhí sí tar éis imeacht nuair a tháinig mé.	She had left when I arrived.	completion before a past point

Similarly, ar tí concerns imminence, not certainty. If you need to say that an intended event was prevented, add the event that intervened: Bhí mé ar tí labhairt, ach chuir sé isteach orm (“I was about to speak, but he interrupted me”). The construction itself only places the action close to beginning.

Finally, keep the after-perfect separate from an ongoing-action construction such as Tá sí ag léamh (“She is reading”). Compare:

• Tá sí ag léamh an leabhair. — She is reading the book; the action is in progress.
• Tá sí tar éis an leabhar a léamh. — She has read the book; the action is complete.
• Tá sí ar tí an leabhar a léamh. — She is about to read the book; the action has not begun.

This three-way contrast—ongoing, completed, and imminent—is one of the best ways to understand what the compound patterns contribute.

Practice Tips

1. Build three-part timelines. Take one action, such as imeacht (“leave”), and say it as ongoing, completed, and imminent: Tá sé ag imeacht; tá sé tar éis imeacht; tá sé ar tí imeacht. Then repeat with a past viewpoint.
2. Transform statements rather than memorising isolated sentences. Change Tá sí tar éis teacht into the negative, question, and past forms: Níl sí..., An bhfuil sí...?, Bhí sí..., An raibh sí...? This reinforces that bí carries the tense and polarity.
3. Practise objects as complete chunks. Write cards with an litir a scríobh, é a cheannach, and an doras a dhúnadh. Then place each chunk after tar éis, i ndiaidh, and ar tí where the meaning makes sense.
