Neither. It's a noun.

No, it is not. It is a verb form (the past and past participle of the verb expand) which can be used as an adjective meaning "increased in size, scope, or extent."
No. The word must is an auxiliary verb indicating a requirement or necessary action.

Is vivid an adverb or an adjective?
Both...
It was a Vivid dream.
Vivid modifies dream, and adverbs cannot modify nouns, so it is and adjective.

Here, vividly modifies the verb, mocked, so it is an adverb since adverbs modify verbs, adjecives, or other adverbs, and adjectives modify only nouns/pronouns.
No. It is a verb or a noun. The noun may be used as a noun adjunct (like an adjective), e.g. "park ranger" or park bench.
Is plethora an adverb or adjective?
It is neither an adjective nor an adverb. "Plethora" is a noun.
Use it like you might use the nouns "abundance" "quantity" or "excess", when what you want to convey is "huge amount" or "overabundance".
I don't think it is often pluralized; have never seen that, anyway.
Also rare would be its adjective form "plethoric", leading to a stretch to make the adverb "plethorically".
Good for "plethora" for being one of those words that has very very few relatives in the language!
No, it is a plural noun. The singular (year) can be a noun adjunct, and there is an adverb, yearly.
"Still" can be an adverb of time, meaning continuing from an unspecified point in the past to the present, as in, "The patient is still alive." This adverb "still" modifies the adjective "alive". "Still" can also modify verbs, particularly progressive ones, and in, "That loudmouth is still talking."
No. Arrested is a verb form that can be used an an adjective.
There is an adverb form "arrestingly" that is used to mean "startlingly."
A large number are formed by adding -LY to the adjective form:

pitiful - pitifully
or replacing E with Y :

able - ably
or changing Y to I and adding LY:
happy - happily
hasty - hastily
