Jumper for woolly garment, initially (4)

Ross

I believe the answer is:

frog

I'm a little stuck... Click here to teach me more about this clue!

'jumper' is the definition.
(something which jumps)

'woolly garment initially' is the wordplay.
'woolly' becomes 'fro' (I can't explain this - if you can you should give a lot more credence to this answer).
'initially' suggests taking the first letters.
The first letter of 'garment' is 'g'.
'fro'+'g'='FROG'

'for' is the link.

Can you help me to learn more?

(Other definitions for frog that I've seen before include "Small creature" , "Croaking amphibian" , "Batrachian" , "Tailless hopper" , "An amphibian; a track plate" .)
