Thank you for all your help!

1 If I want to tell someone to get off a bus --> Jump out! 2 If I want to tell someone to jump down from a table --> Jump down! 3 If I want to tell someone to jump on a chair --> Jump on the chair! Jump up on the chair! 4 If I want to tell someone to jump over an obstacle --> Jump over! 5 If I want to tell someone to jump out the window. --> Jump out!

1. Jump off is not commonly used in this instance. "Hop off/on a bus" is more common. 2. Your grammar here - "jump down FROM a table" the from* is very important:) Yes, jump down is okay, but if you are a parent you would probably simply say "come down/come down from there!" If you are a friend who is amused you would say "jump off!" Because its entertaining to see someone jump down from a table. 3. Jump on a chair is more common. Jump up is usually used for very high distances 4. Jump over a hold? Or a whole? Which do you mean? Simply jump! Can be used. "Jump over" is used in the sentence, "jump over the puddle!" 5. JUMP!!!!!
