Relative Adverbs: Where, When, Why

Replace preposition + which.

Examples

  • That's the café where we met.

Key rules

  • Where refers to places, when to times, why to reasons
  • Where = in/at which, when = on/at which
  • Why is often dropped after the reason
  • Do not repeat the preposition after where

Common mistakes

  • This is the house where I live in → This is the house where I live
  • The day when we met was Monday
💡 Tip: If the clause has a full subject and verb, use a relative adverb.
