Drive off

SHOO

Think of the sound you might make to urge a stray cat away from your doorstep.

"Drive off" is a playful hint where "drive" suggests pushing something away, like you would with an animal or person. The answer "SHOO" fits because it’s the sound or word you’d use to chase something off—like shooing a cat from the table. The clue cleverly turns a literal action ("drive") into a casual, onomatopoeic command.
