Possibly Rice has penned this? (5)
I believe the answer is:
lyric
'penned this?' is the definition.
The definition suggests a singular noun which matches the answer.
'possibly rice has' is the wordplay.
'has' indicates the answer is hidden within the clue.
'LYRIC' is hidden within 'possibly rice'.
Can you help me to learn more?
(Other definitions for lyric that I've seen before include "Text of a popular song" , "Short poem of songlike quality" , "Of poetry that expresses thoughts and feelings" , "A song or poem" , "part of song" .)
