Senior academic mostly giving one side of story? (5)
I believe the answer is:
recto
'one side of story?' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'senior academic mostly' is the wordplay.
'senior academic' becomes 'rector'.
'mostly' means to remove the last letter (most but not all of the word).
'rector' with its final letter removed is 'RECTO'.
'giving' is the link.
Can you help me to learn more?
(Other definitions for recto that I've seen before include "Right-hand pages of book" , "No leaves left" , "front page" , "one side" , "right page" .)
