He wrote poems and odd prose (3)
I believe the answer is:
poe
'he wrote poems' is the definition.
The definition suggests a singular noun which matches the answer.
'odd prose' is the wordplay.
'odd' means one should take alternating letters.
The alternating letters of 'prose' are 'POE'.
'and' acts as a link.
Can you help me to learn more?
(Other definitions for poe that I've seen before include "American author, d. 1849" , "Fall of House of Usher author" , "Edgar Allan . . ., American writer of horror stories" , "Entrance rooms; seeks support from" , "Edgar Allan ---, poet more famous for his gothic short stories" .)
