Prefixes are word parts that are added to the beginning of a word to change its meaning. Some examples of prefixes include:
* un- (undo, unhappy)
* re- (redo, reread)
* pre- (pre-game, pre-paid)
* mis- (misunderstand, misspell)
However, "worthy" itself is not a prefix. It can be used to describe something or someone as deserving of respect, admiration, or consideration.
Perhaps you're thinking of a word that uses "worthy" as part of its meaning, like:
* Worthwhile (meaning something that is valuable or important)
* Worthy of (meaning deserving of something specific)
Could you clarify your question? Maybe you're looking for a word that means something like "deserving of respect" or "valuable"?
