Question

multiple-choice question
which word doesnt show onomatopoeia?
walk
pow!
screech
ruff, ruff

Explanation:

Onomatopoeia refers to words that imitate the sound they describe. "Pow!", "screech", and "ruff, ruff" all mimic specific sounds (an explosion, a harsh high-pitched noise, a dog's bark respectively). "Walk" describes an action, not a sound, so it is not onomatopoeia.

Answer:

walk
