Result of finding a change of diet a bit humdrum? (6)
I believe the answer is:
tedium
'humdrum?' is the definition.
(thesaurus)
'result of finding a change of diet a bit' is the wordplay.
I cannot really see how this works, but
an anagram of 'diet' is 'tedi' which is within the answer.
The remaining letters 'um' 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 tedium that I've seen before include "Banality" , "'Boredom, ennui (6)'" , "boring" , "Routine" , "Boredom, mental weariness" .)
