Cries when some of the boys get so upset (4)
I believe the answer is:
boos
'cries' is the definition.
The definition and answer can be both related to communication as well as being plural nouns.
Perhaps they are linked in a way I don't understand?
'some of the boys get so upset' is the wordplay.
'some' says to take the initial letters.
'get' means one lot of letters go next to another.
'upset' indicates an anagram.
The first letters of 'of boys' is 'ob'.
'ob'+'so'='obso'
'obso' with letters rearranged gives 'BOOS'.
'when' acts as a link.
Can you help me to learn more?
(Other definitions for boos that I've seen before include "Shows disapproval" , "Shouts of disapproval" , "Shouts of derision" , "Catcalls" , "Sounds of disapproval" .)
