Small jumper designed for golf (4)
I believe the answer is:
frog
'small jumper' is the definition.
'frog' can be an answer for 'jumper' (something which jumps). I am not certain of the 'small' bit.
'designed for golf' is the wordplay.
'designed' indicates anagramming the letters (designed with the letters).
'golf' becomes 'g' (phonetic alphabet: alpha, bravo, charlie etc.).
'for' is an anagram of 'fro'.
'fro'+'g'='FROG'
Can you help me to learn more?
(Other definitions for frog that I've seen before include "in grass?" , "throat problem" , "Leaping amphibian" , "contribution to coughing?" , "Tailless hopper" .)
