The suffix -ive turns words into adjectives that describe a quality, tendency, or relationship. When you add -ive to a verb or noun, you create a word that means “having the nature of” or “tending to” something.

Look at how it works: “create” becomes creative (tending to create), “act” becomes active (tending to act), “support” becomes supportive (giving support). The suffix transforms the root word into a descriptor that tells you what something is like or what it does.

You'll find -ive everywhere in English. A talkative person talks a lot. An expensive item costs a lot of money. A defensive player focuses on defense. Notice how the suffix carries the idea forward: if something is explosive, it has the quality of exploding; if someone is imaginative, they use their imagination readily.

Sometimes -ive appears in words where the root isn't obvious anymore, like massive or positive, but the suffix still does its job of turning the word into an adjective. Once you recognize -ive, you'll spot it constantly, and you'll understand that these words are describing tendencies, qualities, or relationships rather than just stating facts.
