Non-professional poem (3)
I believe the answer is:
lay
This clue is a double definition.
'non-professional' is the first definition.
(I've seen this before)
'poem' is the second definition.
(lay is a kind of poem)
(Other definitions for lay that I've seen before include "Was lying" , "Put down; lyric" , "Put down an old song" , "Set (table)" , "Narrative poem" .)
