Sonnets are lyric poems that often contain figurative language. which parts of shakespeare's sonnet 116 are examples of repetition

Repetition, in literature, is a device that repeats the same words or phrases multiple times (at least two or three) to make an idea clearer and more memorable. Usually, the repetition is in the same line as the starting word/phrase, but can be repeated later in the same piece.

In this case, I believe the answer you are looking for is "Love is not love  Which alters when it alteration finds,"  and "Or bends with the remover to remove:"

"Love" is being repeated here, as is "alters" in the form of "alteration" and "remover" to "remove"

Sorry this answer is late, I'll put it here for anyone still looking.
