No time for equestrian sport - later in the day? (7)
I believe the answer is:
evening
'the day?' is the definition.
(evening is a kind of day)
'no time for equestrian sport later in' is the wordplay.
I cannot really see how this works, but
'no' could be 'n' (common abbreviation) and 'n' is found within the answer.
'in' is within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for evening that I've seen before include "Pressing - time of day" , "Levelling late in the day" , "time for putting feet up?" , "'Soup of the - - '" , "Levelling the score" .)
