In Romeo and Juliet in act 2 scene 2, Romeo says With love’s light wings did I o’erprech these walls.

That means:
I Flew over these walls with the light wings of love. Stone walls can’t keep love out.

The question is what language techniques did Shakespeare used here?

what is the question?

explanation:

type of error:

the error in the sentence is a "dangling modifier". a dangling modifier is a phrase, word or clause that "dangles" because there is not target to modify. in this case, "after mopping the floor" is the dangling modifier since it has no word to modify. the noun "house" cannot mop the floor; therefore there is a mistake in the writing of the sentence.
