Maybe Laurel’s recited a piece of poetry (6)
I believe the answer is:
'piece of poetry' is the definition.
(group of lines in a poem)
'maybe laurel's recited a' is the wordplay.
'maybe laurel' becomes 'stan' (comedian Stan Laurel is an example).
'recited' becomes 'z' (I am not sure about this - if you are sure you should believe this answer much more).
Can you help me to learn more?
(Other definitions for stanza that I've seen before include "Lines often repeated" , "Group of lines in a poem, play, etc" , "Chunk of poetry" , "Fixed number of lines of verse" , "Group of lines of verse" .)
