Slipped

He slipped the pen off the desk and into his pocket.

The sun slipped below the horizon, leaving a colorful sky behind.

He slipped on the wet steps and tumbled down the stairs.

The nurse slipped and gave the patient the wrong medication.

She slipped on the rug and nearly fell down the stairs.

The doctor slipped and prescribed the wrong medication.

She slipped on the wet spot in the kitchen and dropped the dishes she was carrying.

I slipped up and forgot to send the important email.
