Here's how to use them:
* Māhoe: This literally means "one placenta". It's used for identical twins who share the same placenta.
* Hoʻokahi makahiki: This literally means "same year". It's used for fraternal twins who develop in separate placentas but are born in the same year.
You can also use "keiki lua" (literally "two children") to refer to twins in general.
