Sounding outstanding, a multifoot thing (3)
I believe the answer is:
ode
'a multifoot thing' is the definition.
I can't judge whether this defines the answer.
'sounding outstanding' is the wordplay.
'sounding' shows a homophone (sound like).
'outstanding' becomes 'owed' (as in an outstanding debt).
'owed' sounds like 'ODE'.
Can you help me to learn more?
(Other definitions for ode that I've seen before include "Literary work" , "Poem expressing noble feelings" , "(Railway)system" , "Lines" , "poetry" .)
