wrink

The term "wrink" is informal and can refer to a wrinkle or crease in something, often fabric or skin. It can be used as a verb to describe the action of making a wrinkle or crease, or as a noun to describe the resulting mark. For example, one might say "don't wrink the shirt" or "there's a wrink in the paper." The origin of the word is likely imitative, suggesting the sound or appearance of a fold.

In a more figurative sense, "wrink" can sometimes be used to describe a minor problem or difficulty, though this usage is less common. For instance, a person might say, "There's a small wrink in our plan." This usage implies a slight imperfection or snag that needs to be smoothed out. The context in which "wrink" is used will generally clarify whether it refers to a physical crease or a metaphorical issue. Its informality means it is rarely found in formal writing.
