Is 'slowly' a noun or verb or adjective or adverb or interjection or preposition or conjunction or pronoun?

Slow can be an adverb, an adjective, or a verb. But not a noun or a pronoun.

---

I'm gong to start with pronouns here: Imagine them to be just shortened nouns. Nouns= people, place or thing. Either it's got a capital letter or think "can I put 'the' or 'a' in front?" 'the car', 'a shoe', Paris. now: 'the slow'? wrong.

NOT a pronoun.

Adverbs describe a verb. Easy to remember because they both say 'verb'. Verbs are action Words- think "can I put 'to' in front?" to walk, to sit, to sleep.

So an adverb needs to go with these Words. They usually end in -ly. She sits rigidly, he sleeps quietly, and I walk slowly.

While slowly can only be an adverb, the Word slow can be either an adjective or an adverb, because in some cases slow became the preferred modifier of the action, e.g Go slow, or The clock runs slow. (which means something different from it running slowly). It can also be a verb, to slow down.
