Prefixes and combining forms—M to N

Want to expand your vocabulary? Figure out the meaning of an unknown word? If so, learning to identify prefixes and understanding their meaning will help you do just that.

What's a prefix? It's a word form that attaches itself to the beginning of another word (the base word) to change the word's meaning. For example, the prefix ex means "former." Connect it to the base word friend, and you're no longer on friendly terms—you're an ex-friend. Big difference.

But what about ex in the word exclude? Is that a prefix, too? No, it isn't. It's a combining form meaning "out," and it attaches itself to a root word, not a base word. Remove the ex, and you're left with the root clude, which makes no sense by itself.

Have fun increasing your word knowledge with these common English prefixes and combining forms.
