One succeeding with broadcast we hear (4)
I believe the answer is:
heir
'one succeeding' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'broadcast we hear' is the wordplay.
'broadcast' becomes 'air' (to air on TV).
'we hear' indicates a 'sounds like' (homophone) clue.
'air' sounds like 'HEIR'.
'with' is the link.
Can you help me to learn more?
(Other definitions for heir that I've seen before include "One due to inherit" , "Beneficiary, inheritor" , "Natural successor" , "One who succeeds" , "Acknowledged beneficiary" .)
