In recital, Frost or Pound will do this with sound (5)
I believe the answer is:
rhyme
'pound will do this with sound' is the definition.
('pound' rhymes with 'sound')
'in recital frost' is the wordplay.
'in recital' indicates a 'sounds like' (homophone) clue.
'frost' becomes 'rime' (rime is a type of frost).
'rime' sounds like 'RHYME'.
'or' acts as a link.
(Other definitions for rhyme that I've seen before include "Charlie Farley for example?" , "'Moon' and 'June' do" , "See 23" , "Versification (which goes with reason)" , "Short piece of verse" .)
