The skill of a tricky manipulator (7,2,4)
I believe the answer is:
sleight of hand
'the skill' is the definition.
(I've seen this before)
'of a tricky manipulator' is the wordplay.
I cannot really see how this works, but
'of' could be 'o' and 'o' is located in the answer.
'a' could be 'an' and 'an' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for sleight of hand that I've seen before include "Skilful deception" , "Manual dexterity in conjuring" , "Doctor or student doctor" , "Prestidigitation" , "Trickery" .)
