How do you say what did yesterday in maori?

You can't directly translate "what did yesterday" into Maori. Maori grammar works differently, and you would need to rephrase the sentence to express the same meaning.

Here are a couple of options, depending on what you want to ask:

1. To ask "What did you do yesterday?":

* "He aha tāu i mahi ai inanahi?" This is a more literal translation, using the past tense "i mahi ai" to ask about something that happened yesterday.

2. To ask about something specific that happened yesterday:

* "He aha te mea i puta i inanahi?" This would translate to "What happened yesterday?"

* "He aha tāu i kai ai inanahi?" This would translate to "What did you eat yesterday?"

Important Notes:

* The word order in Maori is different from English.

* The word "inahi" means "yesterday".

* The word "ā" is used to make a question.
