Understanding An Aimsir Fháistineach
The aimsir fháistineach is how you talk about future actions in Irish. Speakers can express plans, intentions, and predictions with it. Learn how it works and start building natural future tense sentences in Irish, but if you haven't learnt the present tense in Irish, we recommend you start there.

Definition and Importance
This tense is key in Irish. You can't talk about plans or expectations without it. It's used in both casual conversation and formal contexts.
In an aimsir fháistineach, verbs are still divided into two main groups: first conjugation (one syllable) and second conjugation (two or more syllables). This distinction determines how endings are applied when forming the future tense. Recognising the verb type early makes it much easier to apply the correct aimsir fháistineach endings consistently.

Rules for Forming An Aimsir Fháistineach
The future tense has some key rules that allow for its consistent structure. Unlike other tenses in Irish, such as the past tense, it's more about endings than changes at the beginning of the verb. You'll soon recognise and apply these rules.
General Rules
The structure is pretty simple. After all, the meaning is in the verb endings. Focus on these patterns to form accurate Irish sentences quickly.
Unlike the past tense, verbs in an aimsir fháistineach do not take a séimhiú or the prefix d’. Instead, the tense is formed mainly through specific endings added to the verb. For negatives, use ní with a séimhiú, and for questions, use an with an urú, which changes the beginning sound of the verb.
