Term no longer in polite use by linguists. Many believe in an Altaic family, comprising Turkish, Mongolian, and others, but all would object strenuously to "simple structure", and what Webster's meant by "low grade" is anyone's guess.

The term Turanian is occasionally met with on the outer fringes of historical linguistics for a wide-ranging proto-family covering Altaic and all sorts of other things: Semitic, Dravidian, anything mysterious that they can make wild connections to.
