Is where a verb?

"Where" is not a verb. It's an adverb that indicates a place or position.

For example:

* Where did you go? (Indicates the location of the action "go")

* I don't know where to find it. (Indicates the location of the action "find")

To make "where" part of a verb, you would need to combine it with a verb, like "wherever" or "whereupon".

For example:

* Wherever you go, I'll follow you.

* Whereupon he stood up and left.
