Answer:
Verb: inspire - Noun: inspiration - Adjective: inspirational / inspiring
Adjective: careful / careless / caring
Explanation:
Derivational suffixes like -ful, -less, -ing, -e, -tion and -al change the meaning of the words they are attached to, as in careful and careless, which are opposites. Besides, they also alter the grammatical category of the words, as in the verb explode, the noun explosion and the adjective explosive.
