In Māori locating what is being spoken about in relation to the speaker and listener is important. Like nei, anei is used when the subject of discussion is located near the speaker. Anei precedes words such as te and ngā. It is also used in combination with words indicating possession or ownership such as ō, tāu, tōu, āu, ōu, tāna, tōna, āna, ōna, etc. Anei usually starts a sentence. Anei is usually used when giving over an object or indicating the position of the object when it is very close to the speaker.
Anei tōu koti.
Here is your coat.
Anei te pata.
Here is the butter.
Anei ngā pepa mō te hui.
Here are the papers for the meeting.
