Is at a noun pronoun or verb?

Answer 1

No, the word 'at' is a preposition, a word, coming in front of a noun or pronoun, telling its relation to another word in a sentence.

Example:

I'm meeting my friends at the mall. (the preposition 'at' relates the noun 'mall' to the verb 'meeting')

A verb is a word for an action or a state of being. In the example sentence, the verb is 'meeting', a word for an action)

A pronoun is a word that takes the place of a noun in a sentence. In the example, the pronoun 'I' is taking the place of the noun (name) for the person speaking)
