Has turned over pages, one chapter relating to poetess (7)
I believe the answer is:
sapphic
'relating to poetess' is the definition.
I can't judge whether this definition defines the answer.
'has turned over pages one chapter' is the wordplay.
I cannot quite understand how this works, but
'pages' could be 'pp' and 'pp' is located in the answer.
an anagram of 'has' is 'sah' which is present in the left over letters.
'one' could be 'i' (Roman numeral) and 'i' is found in the answer.
'chapter' could be 'c' (abbreviation) and 'c' is located in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for sapphic that I've seen before include "emale poetry" , "related to lyric poet" , "Poetic gem" , "Relating to a Greek female poet" , "Like poet's appeal" .)
