Female on meadow in little jumper (4)
I believe the answer is:
flea
'little jumper' is the definition.
'flea' can be an answer for 'jumper' (something that jumps). I'm not sure about the 'little' bit.
'female on meadow' is the wordplay.
'female' becomes 'f' (abbreviation).
'on' means one lot of letters go next to another.
'meadow' becomes 'lea' (a lea is a grassy area).
'f'+'lea'='FLEA'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for flea that I've seen before include "Wingless, jumping insect" , "Leaping insect" , "Small jumper in small circus" , "Jumping, biting insect" , "Member of a circus?" .)
