The cat jumped over the fence.

My son (7 year old) asked why can't we just say "the cat jumped the fence?"

'jumped' without 'over' has different meanings.

jump: to attack someone physically

They jumped me and stole my wallet.


to jump the gun: for a competitor to start a race before the starting gun is fired

"prep. 2. a. Above and across from one end or side to the other: a jump over the fence."

We can, but there are times when "over" is called for, as in "the cow jumped over the moon". You can't make that "the cow jumped the moon", partly because the moon is not something that gets jumped.
