“The whole island was shuttering” LotF

What do you need help on? I don’t understand

I’m confused is there any more information? Is this a passage that I need to read?

This is what i found “an elliptical clause is a type of dependent, or subordinate, clause that is missing a word or words. often, the missing part is a verb or verb phrase. while elliptical clauses are acceptable to use, they can sometimes cause confusion for writers and readers, especially when the sentence ends with a pronoun.” i hope this you for what your looking for. can you plz mark me brainliest?
