You're proofreading your friend's party invitation before it goes out to 200 guests. Choose the correct word to save them from eternal embarrassment!

"_____ going to love the surprise we have planned at _____ house over _____."

The correct answer is They're / their / there.

They're = "they are" (contraction) — "They are going to love..." Their = possessive — "at their house" (the house belonging to them) There = a place — "over there" (indicating location) This tricky trio trips up even native speakers!
