The preposition generally stands immediately before the word it governs; as, We live in Toronto.
1. When the noun has attributive adjectives, the preposition precedes the adjective; as, I walked through a beautiful park.
2. When the object of the preposition is a relative, the preposition sometimes stands at the end of the clause; as, My brother owns the building which he lives in, [in which he lives is preferable.]
3. In poetry the preposition often follows its object; as, The heavy night hung dark the hills and waters o’er.
4. When two verbs or adjectives in association are followed by different prepositions, the prepositions must be repeated after each; as, He found him a man whom he agreed with on a few subjects, and differed from on many; or, He found him a man with whom he agreed on a few subjects, from whom he differed on many.
