Is the above sentence correct with the usage of 'better than' followed by 'before'? Usually, (better) than is followed by a noun / pronoun, but here, 'before', an adverb, is used. Is it fine? If so, please explain the sentence structure.
Before can be used in the following ways: as a conjunction (connecting two clauses): Think carefully before you choose. as a preposition (followed by a noun): We’ll finish the project before Christmas. as an adverb (without a following noun): I’d met him once before.
