In plain English: Huge means extremely big or very large.

Usage: Use huge to describe something that is extremely big in size, amount, or degree. It often carries a stronger sense of impressiveness than simply saying something is large.
The word huge entered Middle English from Old French, where it originally meant "high" or "lofty." Linguists believe its ultimate roots lie in a Germanic term for hill or mound that is related to the modern English word high.
