See post diverted to one producing original lines (7)
I believe the answer is:
poetess
'one producing original lines' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'see post diverted' is the wordplay.
'diverted' indicates anagramming the letters (letters must be diverted to different positions).
'see'+'post'='seepost'
'seepost' is an anagram of 'POETESS'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for poetess that I've seen before include "Sappho, for one" , "Emily Dickinson perhaps" , "Lady of verse" , "See spot (anag)" , "Female writer of verse" .)
