I'm (hesitantly) getting into beat for this verse form (8)
I believe the answer is:
limerick
'this verse form' is the definition.
(limerick is a kind of verse form)
'i'm hesitantly getting into beat' is the wordplay.
'hesitantly' becomes 'er' (I've seen this in other clues).
'getting into' indicates putting letters inside.
'beat' becomes 'lick' (synonyms).
'im'+'er'='imer'
'imer' inserted within 'lick' is 'LIMERICK'.
'for' is the link.
(Other definitions for limerick that I've seen before include "Type of humorous verse" , "[EDWARD LEAR] work" , "Short amusing verse" , "Humorous short poem" , "Humorous five-line verse" .)
