How do you say teen in hawaiian?

There isn't a direct translation for "teen" in Hawaiian. The concept of "teenager" is a modern one and doesn't have a specific word in traditional Hawaiian culture.

You could describe someone in their teens by using:

* 'Ōpio: This means "youth," "young man," or "young person." You could say "He is an 'ōpio" (He is a young person) or "ʻOia he 'ōpio" (She is a young person).

* 'Ōpiopio: This is the plural form of 'ōpio.

* Kahiakahi: This means "young," "youth," or "child." You could say "He kahiakahi" (He is young) or "ʻOia kahiakahi" (She is young).

* Nā Kamali'i: This means "children." It can be used to refer to a group of teenagers.

The most appropriate way to describe someone in their teens will depend on the context of the conversation.
