Disregard for commentator’s dexterity (7)
I believe the answer is:
sleight
'dexterity' is the definition.
(I know that dexterity can be written as sleight)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for sleight that I've seen before include "Hits leg (anag) - cunning" , "Handy skill" , "Artful trick" , "Conjuror uses this" , "Tricky cunning" .)
