Adverb
An adverb modifies a verb. Most adverbs end in ~ly, but not all do: “now”, “later”, “still” “again” “moreover”, “further”, “also”, “besides”, “too” can all function as adverbs and you can of course create adverbial phrases like “on top of”, “over and above”, “into the bargain”, “by the same token” and so tiresomely on.
Adverbs are not welcome in legal writing, or any other literature that aspires to wit or elegance. If you find yourself resorting to an adverb, always look first for a better verb.
