Poem one cheerleader put on record (4)
I believe the answer is:
epic
'poem' is the definition.
(I know that epic is a type of poem)
'one cheerleader put on record' is the wordplay.
'one cheerleader put' becomes 'ic' (I can't justify this - if you can you should believe this answer much more).
'on' says to put letters next to each other.
'record' becomes 'EP' (abbreviation for extended play record).
'ic' after 'ep' is 'EPIC'.
Can you help me to learn more?
(Other definitions for epic that I've seen before include "Impressive scope" , "imposing" , "Exodus, say" , "Long poem set in nice picture" , "Colossal" .)
