Expect there's a load to listen to? (5)
I believe the answer is:
await
'expect' is the definition.
('await' can be a synonym of 'expect')
'a load to listen to?' is the wordplay.
'load' becomes 'weight' (I have seen 'Heavy load ' mean 'weight' so perhaps 'load' could also mean 'weight').
'to listen to?' shows a homophone (sound like) (I've seen 'listened to' mean this).
'weight' sounds like 'wait'.
'a'+'wait'='AWAIT'
'there's' acts as a link.
(Other definitions for await that I've seen before include "To be in store for (someone)" , "Stay around for" , "Look for (future event)" , "Remain for (someone)" , "Expect, anticipate" .)
