Late at night, the clicketty-clack of horse hooves on the cobblestones kept me awake.

Her high heels click-clack across the marble floor as she hurried to the interview.

She strode into the empty station, click-clacking down the platform with every step.

The workshop was full of old clack boxes that clicked and whirred whenever someone walked by.

The clack doors in the old mansion kept slamming shut with a sharp, rhythmic sound.
