Little jumper knitted for girl initially (4)
I believe the answer is:
frog
'little jumper' is the definition.
'frog' can be an answer for 'jumper' (something which jumps). I am not sure about the 'little' bit.
'knitted for girl initially' is the wordplay.
I cannot really see how this works, but
an anagram of 'for' is 'fro' which is present in the answer.
'girl' could be 'g' and 'g' is present in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for frog that I've seen before include "Amphibian (lodged in the throat?)" , "Obstruction, in throat" , "Croak in the throat?" , "Leaping amphibian" , "Amphibian - depression in brick" .)
