IPA: /ˈpʌkərər/
KK: /ˈpʌkərər/
A person or thing that causes something to wrinkle or gather together in folds.
The puckerer made the fabric look more interesting with its unique texture.
Puckerer is formed from "pucker" (of uncertain origin, possibly imitative of the action of puckering) and the suffix "-er" (meaning a person who performs an action). The word refers to a person who puckers, typically in the context of making a facial expression or manipulating something to create folds or wrinkles.
Think of someone who 'puckers' — the '-er' indicates that this person is doing the action of puckering, which helps you remember that a puckerer is someone who puckers.
