Subfamily

The Bantu languages are a subfamily of the Niger-Congo languages.

Hebrew and Phoenician belong to the same language subfamily and are practically the same.

The discovery marks the first time since nineteen twenty-three that a new ant subfamily has been identified.

There is a handy font editor tool in the engine, where you can import your font and create family and subfamily for your font (for example, the same font can have a family for its bold, italic, light, and dark style as its subfamily).
