Stumbles

The horse has four legs and still stumbles sometimes.

The horse of a hurried man is often sick, but that of a lazy man often stumbles.

The man stumbles, as if he is about to fall.

Forget about robotics. Not even the beetle can find sure footing and stumbles randomly.

Tom stumbles and falls. Cursing, he picks himself up, brushing off his pants.

He stumbles over his words.

Everyone stumbles from time to time.

A horse that stumbles has four legs.
