Humour child with rebellious urge (6)
I believe the answer is:
kidney
'humour' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'child with rebellious urge' is the wordplay.
'child' becomes 'kid' (synonyms).
'with' says to put letters next to each other.
'rebellious' says the letters should be written in reverse.
'urge' becomes 'yen' (I've seen this before).
'yen' in reverse letter order is 'ney'.
'kid'+'ney'='KIDNEY'
Can you help me to learn more?
(Other definitions for kidney that I've seen before include "body part" , "Organ at back of abdomen" , "temperament" , "Glandular organ that removes waste matter from blood" , "class" .)
