Is an adverb a descriptive word?

It's not quite that simple! While adverbs often describe how, when, where, or to what extent something happens, they don't always function solely as descriptive words.

Here's a breakdown:

* Descriptive Adverbs: These adverbs provide more information about the verb, adjective, or other adverb they modify. They answer questions like:

* How? (She walked *quickly*)

* When? (He arrived *late*)

* Where? (They looked *upwards*)

* To what extent? (It was *extremely* hot)

* Adverbs as Conjunctions: Some adverbs can connect clauses, acting as conjunctions.

* However, therefore, moreover, nevertheless

* Adverbs as Intensifiers: These adverbs emphasize the word they modify.

* Very, extremely, really, quite

So, are adverbs descriptive words? Yes, in many cases. But they can also serve other grammatical functions. It's more accurate to say adverbs modify other words and phrases, adding extra information or nuance.
