Senior academic mostly giving one side of story? (5)
I believe the answer is:
recto
'one side of story?' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Maybe they are linked in a way 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 last letter taken off is 'RECTO'.
'giving' acts as a 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" .)
