Enjoyable day is fast-moving, meal ultimately is skipped (10)
I believe the answer is:
satisfying
'enjoyable' is the definition.
(thesaurus)
'day is fast-moving meal ultimately is skipped' is the wordplay.
I cannot really understand how this works, but
'day' could be 'sat' (abbreviation for Saturday) and 'sat' is found within the answer.
'is' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for satisfying that I've seen before include "Meeting (requirements)" , "enough?" , "Meeting (needs, etc)" , "filling" , "Pleasurable" .)
