Jump is one of those urgent words.
A few phrases come into mind:
Jump for joy!…Jump around!..Jump into your life!
Emphatically… jump means to do it right now.
From the obvious action of jumping, like off a cliff or jumping on a trampoline, it’s one of those command words that urges one to do the action immediately.
A person who is told to Jump! doesn’t have time to sit and reflect.
They just have to do it!
