Regularly see defeat? (9)
I believe the answer is:
routinely
'regularly' is the definition.
(thesaurus)
'see defeat?' is the wordplay.
I cannot really understand how this works, but
'see' could be 'ely' (see is a place with a cathedral - e.g. Ely) and 'ely' is found within the answer.
'defeat?' could be 'rout' (rout is a kind of defeat) and 'rout' is found in the answer.
The remaining letters 'in' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for routinely that I've seen before include "typical fashion" , "according to custom" , "As a matter of course" .)
