Expressions of grief upset boss (4)
I believe the answer is:
sobs
'expressions of grief' is the definition.
The answer and definition can be both related to communication as well as being plural nouns.
Perhaps you can see a link between them that I can't see?
'upset boss' is the wordplay.
'upset' indicates an anagram.
'boss' anagrammed gives 'SOBS'.
Can you help me to learn more?
(Other definitions for sobs that I've seen before include "Weeps noisily" , "cries uncontrollably" , "Weeps heavily for boss" , "Cries loudly" , "Weeps audibly" .)
