he aha ... ai

Asking Why an Event Happens

Level 4

Past: he aha + subject + i + action + ai. Future: use e before the action.

How It Works

For a positive past event, use he aha + subject + i + action phrase + ai. The future-event frame uses e before the action. A personal name retains its subject article a; the predicate takes no person or number endings. Modifiers belonging to the action phrase precede ai, while a destination can follow it with its normal ki marking.

Compare I hoki wawe koe, “You returned early,” with He aha koe i hoki wawe ai?, which requests the reason. Past nonoccurrence has the separate frame he aha + subject + i kore ai e + action: here ai follows kore, and e introduces the action. When the event is already understood, He aha ai? means “Why?”.

Examples (3)

  1. He aha koe i hoki wawe ai?

    Why did you return early?

    Ai follows the action and its modifier.

  2. He aha ngā manuhiri e haere ai ki reira?

    Why will the visitors go there?

    The future-event frame retains the destination phrase.

  3. He aha a Mere i kore ai e waea mai?

    Why did Mere not phone me?

    Ai follows kore; mai directs the phoning toward the speaker.

Learn This First

Introduce separate positive past, future and past-negative why patterns. The returning example places ai after the action phrase, whereas the nonphoning example uses i kore ai e; the complete frame links the requested reason to the specified event.
