This name comes from the root Anas in Arabic and the verb Ya'anas and the name Anas for the male and Anisa for the female or (Aneesa) the last letter is H when you have no words to follow it but if you do it will be Anisat and the "t" at the end of it makes the male name Anas a female name. So Anisa is the same as Anisah like Sarah can be written Sara. The meaning of the root Anas is Close and that is the nearest to the meaning in Arabic so for example domestic animals are called must'anasa animals Because Man has made it friendly to him with time and close. When you say Mary is anisat Mike it means she is a close friend to Mike.
