関係代名詞の使い方, part 19: 関係代名と前置詞

Last time I was talking about stranded prepositions and relative clauses.

• stranded preposition 残置前置詞｛ざんち ぜんちし｝

Like I said yesterday, native speakers use this pattern all the time, even though some really strict teachers don't like it.

Start with a sentence with a prepositional phrase.

• prepositional phrase 前置詞句
• I was studying programming in this room on Sunday evening.

Take the object of the preposition, and make a new sentence

• prepositional object 前置詞付き目的語
• This room is a laboratory at my university.
  

Now put the two together with a relative pronoun.

• This room, which I was studying programming in on Sunday, is a laboratory at my university.

The preposition is said to be "stranded" because there's no object right after it.

• 擱座 (かくざ) (n,vs) running aground; stalled; stranded;

I turned off the lights and just used a lamp. That's more comfortable than the florescent lights. The lights (which) I turned off were fluorescent. Maybe I'll be doing the same thing this Sunday.

• 蛍光灯 (けいこうとう) (n) (1) fluorescent lamp; fluorescent light;

Enjoy your weekend!
