KK: /ˈzɪpərd/
Closed or fastened using a zipper, or having zippers as part of its design.
She wore a zippered jacket that kept her warm in the cold weather.
Zippered → The word is derived from 'zipper' (a modern English term, likely a blend of 'zip' meaning to move quickly and 'zipper' itself, which is a trademarked name from the 1920s for a fastening device) and the suffix '-ed' (indicating a past participle or completed action). The term 'zippered' refers to something that has been fastened or closed using a zipper.
Think of the action of 'zipping' something up quickly, and remember that 'zippered' means something that has been fastened with a zipper.
