Basho describes penning poems (4)
I believe the answer is:
odes
'poems' is the definition.
(ode is a kind of poem)
'basho describes penning' is the wordplay.
'ODES' is hidden within the letters.
However, I am not sure how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for odes that I've seen before include "Lays" , "Poets write them" , "Lyric poems" , "Lyrical poems" , "Keats was fond of them" .)
