Crafty about some of the camels ponging a bit (6)
I believe the answer is:
smelly
'the camels ponging a bit' is the definition.
I can't tell whether this definition defines the answer.
'crafty about some' is the wordplay.
'crafty' becomes 'sly' (sly can mean crafty or cunning).
'about' indicates putting letters inside.
'some' becomes 'mel' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'sly' enclosing 'mel' is 'SMELLY'.
'of' is the link.
Can you help me to learn more?
(Other definitions for smelly that I've seen before include "Stinking" , "Having a bad odour" , "With unpleasant odour" , "Foetid" , "Unpleasant on the nose" .)
