He wrote poems about steak! (5)
I believe the answer is:
keats
'he wrote poems' is the definition.
The definition suggests a singular noun which matches the answer.
'about steak' is the wordplay.
'about' is an anagram indicator.
'steak' with letters rearranged gives 'KEATS'.
Can you help me to learn more?
(Other definitions for keats that I've seen before include "John --, Romantic poet" , "English poet, 1795-1821" , "Early 19th century poet" , "second-hand Homer reader" , "Endymion, Lamia poet" .)
