Toilet mostly clear after fellow flushed (6)
I believe the answer is:
florid
'flushed' is the definition.
(I've seen this before)
'toilet mostly clear after fellow' is the wordplay.
I cannot really understand how this works, but
'clear' could be 'rid' (synonyms) and 'rid' is found within the answer.
'fellow' could be 'f' (abbreviation - of a society etc.) and 'f' is found in the answer.
The remaining letters 'lo' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for florid that I've seen before include "Elaborately intricate" , "(Of language) flowery" , "Excessively ornate" , "Overly ornate" , "Elaborately ornamented" .)
