Rogue told to choose a new jumper for collection (8)
I believe the answer is:
picaroon
'rogue' is the definition.
(I've seen this before)
'told to choose a new jumper for collection' is the wordplay.
'told' indicates a 'sounds like' (homophone) clue.
'to choose' becomes 'pick' (picking is a kind of choosing).
'a' becomes 'an'.
'new jumper' becomes 'roo' (short for kangaroo. I am not sure about the 'new' bit.).
'for collection' means one lot of letters goes inside another (inserted letters are collected by others).
'pick' sounds like 'pic'.
'an' going around 'roo' is 'aroon'.
'pic'+'aroon'='PICAROON'
Can you help me to learn more?
(Other definitions for picaroon that I've seen before include "rogue" , "Pirate" .)
