English

Noun

megamillion ‎(plural megamillions)

1. (informal) A great number of millions.

Usage notes

The word does not come from the SI prefix mega- but from concatenation with the informal word mega. Thus the word means "a great number of millions", not a thousand million or a million million. The noun is mainly used attributively.
