Argument with editor didn't go well (7)
I believe the answer is:
clashed
'well' is the definition.
The answer and definition are not the same part of speech. However, adjectives and past participle verbs sometimes mean the same thing.
'argument with editor didn't' is the wordplay.
I cannot really see how this works, but
'editor' could be 'ed' (abbreviation) and 'ed' is located in the answer.
The remaining letters 'clash' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'go' acts as a link.
Can you help me to learn more?
(Other definitions for clashed that I've seen before include "Was incompatible" , "Came into conflict" .)
