A while before I found Textkit, I came across a note in Wheelock that said adjectives sometimes have adverbial strength or power or some related word. I translated the indicated adjectives as adverbs in English. Is this correct, or is there some other way to translate them?
A lot depends upon context as to whether an adjective functioning adverbally in Latin should be so rendered in English. If you post the Latin, it will be easier to see how your translations fare.
The most common inflection of adjectives that can be translated in an adverbial sense into English are the neuter plurals and some old (generally neuter) accusative singular adverbs.
