Anticipate something heavy, by the sound of it (5)
I believe the answer is:
await
'anticipate' is the definition.
(I know that anticipate is a kind of await)
'something heavy by the sound of it' is the wordplay.
'something' becomes 'a' (I can't explain this - if you can you should give a lot more credence to this answer).
'heavy' becomes 'weight' (I've seen this before).
'by the sound of it' shows a homophone (sound like).
'weight' sounds like 'wait'.
'a'+'wait'='AWAIT'
Can you help me to learn more?
(Other definitions for await that I've seen before include "Look out for - expect" , "Be in expectation of (an event)" , "Look for (future event)" , "Remain in expectation for (an occurrence)" , "Hope for" .)
