English glee is affected by verses (7)
I believe the answer is:
elegies
'verses' is the definition.
The definition and answer can be both related to communication as well as being plural nouns.
Perhaps there's an association between them I don't understand?
'english glee is affected' is the wordplay.
'english' becomes 'e' (abbreviation**).
'affected' indicates an anagram.
'glee'+'is'='gleeis'
'gleeis' with letters rearranged gives 'legies'.
'e'+'legies'='ELEGIES'
'by' acts as a link.
Can you help me to learn more?
(Other definitions for elegies that I've seen before include "Mourning songs" , "Lamenting poems" , "Laments for the dead" , "Poems of mourning" .)
