Regardless of which contest one's competing in? (2,3,5)
I believe the answer is:
in any event
'regardless' is the definition.
(I've seen this before)
'which contest one's competing in?' is the wordplay.
I cannot really see how this works, but
'contest' could be 'event' (I've seen this before) and 'event' is located in the answer.
'in?' could be 'in' and 'in' is found in the answer.
'one' could be 'an' (I've seen this in other clues) and 'an' is located in the answer.
A single letter 'y' remains which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).
'of' acts as a link.
Can you help me to learn more?
(Other definitions for in any event that I've seen before include "Whatever happens" , "Regardless of circumstances" , "How one might describe a decathlete's skill" , "Anyway" , "Where all-round sportsman may compete" .)
