Complete this angry traveler's online review by choosing the correct relative clause for each blank.

The creepy hotel where we stayed was supposedly haunted.

Sir Reginald , who haunts the third floor, kept stealing my socks every night.

The only suitcase that survived the trip is now full of green slime!

The correct sentences are: The creepy hotel where we stayed was supposedly haunted. Sir Reginald**, who haunts the third floor,** kept stealing my socks every night. The only suitcase that survived the trip is now full of green slime!

where we stayed defines exactly which hotel is being talked about, so no commas are needed. We use where for places (or in which).

Sir Reginald is a specific name, so the clause just adds extra information. This requires commas. We cannot use that after a comma!

The only suitcase requires a defining relative clause to specify it. We use that for things, and no commas are used.
