Unnecessary adjective clause that refers to complete sentences | Grammar Guy
Unnecessary adjective clause that refers to complete sentences Sometimes an adjective clause comes after the entire sentence and refers to the entire sentence instead of to a single noun; for example: - John made high grades on his exam, which made his parents happy.
When the adjective clause refers to the entire sentence, only the relative pronoun "which " can begin the clause. Note that a comma must be included. Otherwise, the adjective clause becomes a necessary clause and will modify only the noun before it; for example: Jim tried to sing at the party which made everyone laugh. The "party" didn't make everyone laugh, "Jim's singing at the party" made everyone laugh.
