Māori Grammar

There are some words which describe an action that can be done on its own, without reference to anything else. For example, I can run. The word "run" is known as an "intransitive verb". There other words that describe an action that does relate to something else. While I can say "I am reading" or "I am singing", it is implied that I am reading something or singing something. I might be reading a book or singing a song. These kind of verbs are known as "transitive verbs".

When giving a command to a person to do something, if the verb is transitive, then we use a passive ending. For example:

Pānuihia!
Read!

Because the verb "read" is transitive (we read something), then the passive ending is used to make this word a command. This true of other words that are transitive. 

Riringihia!
Pour!

Kohia ngā parapara.
Collect up the rubbish.

When giving commands, we do not use a passive ending for intransitive verbs. For example, the word "stand" is intransitive and so would simply say: e tu! to give someone the command to stand - it does not take a passive ending.

When giving commands using the passive, we do not use i or ki to identifty the object of the sentence. For example, we would say:

Tikina tō pōtae.
Fetch your hat

and not:

*Tikina i tō pōtae.*
Fetch your hat

Compare the following, where an active command uses ki but the passive command does not:

Titiro ki te mainga!
Look at the mountain!

Titirohia te mainga!
Look at the mountain!
