Adverbs are used mostly to describe #verbs# which are the #action# in the sentence, but they can describe other components of the sentence structure.
Explanation:
#his# socks, #his# idea, #his# mother, all describe #objects# that belong to him. The pronoun is a result of referencing a subject indirectly. See below:
#His# dream in tatters, Neil decided to return to the drawing board.
The possessive pronoun #his# is followed immediately by the object #dream# and later the subject #Neil#.
