The attitude of a cricketer taking a knock (6)
I believe the answer is:
stance
'the attitude' is the definition.
(stance is a kind of attitude)
'a cricketer taking a knock' is the wordplay.
I cannot really understand how this works, but
'a' could be 'an' and 'an' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
'of' is the link.
Can you help me to learn more?
(Other definitions for stance that I've seen before include "Attitude, point of view" , "Player's posture for making, say, golf stroke" , "Enacts (anag)" , "position when batting" , "Golfer's position for making stroke" .)
