jumpy

Nervous and excited.

It was the butler who saw him go. Twelve o'clock at night and raining hard. So next night I was up at the house and, sure enough, master was off again. Stephens and I went after him, but it was jumpy work, for it would have been a bad job if he had seen us.

Tending to jump; full of jumps.

We moved at a good clip, so I reached up to pull shut the window coverings, just in case this jumpy frog decided to escape.

Meanwhile, the car pursued its jumpy course, and I could not prevent myself laughing.
