The suffix -age attaches to the end of words to create nouns, often showing an action, a result, a state of being, or a collection of things.

When you add -age to pack, you get package: something that has been packed. Add it to store and you get storage: the act of storing things or a place where things are stored. Wreckage means the broken remains after something has been wrecked. Courage describes the state of being courageous.

Sometimes -age creates words for collections: baggage means all your bags taken together, and foliage refers to all the leaves on trees and plants in an area.

You'll also see -age in words describing processes or costs: postage is what you pay to mail something, and dosage refers to the amount of medicine given at one time.

Notice how -age often makes abstract ideas feel more concrete: break is just an action, but breakage becomes a thing you can measure, count, or clean up. When you understand -age, you can often figure out unfamiliar words: if you see seepage, you know it must involve something seeping, even if you've never encountered the word before.
