Monotonous morning in more ways than one (4)
I believe the answer is:
same
'monotonous' is the definition.
(thesaurus)
'morning in more ways than one' is the wordplay.
I cannot really see how this works, but
'morning' could be 'am' (as in 12:00 AM) and 'am' is present in the answer.
The remaining letters 'se' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for same that I've seen before include "If - be the food of love, play on (Twelfth Night)" , "Identical, not different" , "Equal in amount or value" , "Identical, unchanged" , "uniform" .)
