Marked description of one who has been in full cry? (11)
I believe the answer is:
tearstained
'been in full cry?' is the definition.
The definition suggests a past participle verb which matches the answer.
'marked description of one' is the wordplay.
I cannot really understand how this works, but
'marked' could be 'stained' (I've seen this before) and 'stained' is present in the answer.
'one' could be 'a' (a thing is one thing) and 'a' is located in the answer.
The remaining letters 'ter' 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).
'who has' is the link.
Can you help me to learn more?
(Another definition for tearstained that I've seen is " Wet from crying".)
