Charly's upset, Maureen's audibly tearful (10)
I believe the answer is:
lachrymose
'tearful' is the definition.
(synonyms)
'charly's upset maureen's audibly' is the wordplay.
I cannot really see how this works, but
'maureen's' could be 'mos' (nickname for Maureen) and 'mos' is found in the answer.
an anagram of 'charly' is 'lachry' which is located in the answer.
A single letter 'e' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for lachrymose that I've seen before include "This is given to crying" , "Weepy" , "In bits" , "showing sorrow" , "Tearful (literary)" .)
