Penempatan Preposisi dalam Relative Clause

Sering kali, ada preposisi dalam klausa relatif (relative clause), dan kata ganti relatif (relative pronoun) adalah objek dari preposisi tersebut. Dalam bahasa Inggris sehari-hari, preposisi biasanya diletakkan di akhir klausa relatif, dan kata ganti dapat disertakan atau dihilangkan. Dalam bahasa Inggris resmi, preposisi diletakkan sebelum kata ganti relatif, sehingga kata ganti relatif tidak dapat dihilangkan. Dalam contoh-contoh di bawah ini, kata ganti dalam tanda kurung dapat dihilangkan.
