What the suffix imp mean?

The suffix "-imp" usually means "one who is" or "one who does". It's often used to form nouns from verbs or adjectives, indicating a person or thing with a particular characteristic or action.

Here are some examples:

* Imp - A mischievous or impish person (from "impish")

* Vamp - One who attracts or seduces (from "vamp" meaning "vampire")

* Wimp - A weak or cowardly person (from "wimp" meaning "weak")

* Simp - Someone who is overly attentive to someone they have romantic feelings for (from "simple" meaning "naive" or "gullible")

It's important to note that "-imp" isn't as common as other suffixes like "-er" or "-or," and its use can be quite informal or slangy.
