Bad ways to trot, possibly (6)
I believe the answer is:
rotten
'bad' is the definition.
(similar in meaning)
'ways to trot possibly' is the wordplay.
'ways' becomes 'en' (I can't explain this - if you can you should believe this answer much more).
'to' is a charade indicator (letters next to each other) (I've seen this in other clues).
'possibly' indicates an anagram.
'trot' is an anagram of 'rott'.
'en' after 'rott' is 'ROTTEN'.
Can you help me to learn more?
(Other definitions for rotten that I've seen before include "Falling to pieces from age or morally contemptible" , "Decayed or detestable" , "Decayed or despicable" , "Dedayed, stinking" , "'Decayed, stinking (6)'" .)
