Jumper fits – take it and tops (5)
I believe the answer is:
roofs
'tops' is the definition.
(I've seen this in another clue)
'jumper fits take it' is the wordplay.
'jumper' becomes 'roo' (short for kangaroo, something which jumps).
'take' is a deletion indicator.
'fits' with 'it' taken out is 'fs'.
'roo'+'fs'='ROOFS'
'and' acts as a link.
(Other definitions for roofs that I've seen before include "Tops of buildings" , "Protective coverings for buildings" .)
