Young sportsman's jumper that is inspiring top for kids (6)
I believe the answer is:
rookie
'young sportsman's jumper that is inspiring top for kids' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'jumper that is inspiring top for kids' is the wordplay.
'jumper' becomes 'roo' (short for kangaroo, something which jumps).
'that is' becomes 'ie' (short for Latin 'id est', 'that is').
'inspiring' means one lot of letters goes inside another.
'top for' indicates taking the first letters.
The first letter of 'kids' is 'k'.
'roo'+'ie'='rooie'
'rooie' placed around 'k' is 'ROOKIE'.
Can you help me to learn more?
(Other definitions for rookie that I've seen before include "untrained soldier" , "untested type" , "New recruit as to army" , "Beginner as in the army" , "Novice" .)
