I’m brought in to sound loud: hope things will improve? (4,3,4)
I believe the answer is:
play for time
'hope things will improve?' is the definition.
(to play for time is to wait for an improvement)
'i'm brought in to sound loud' is the wordplay.
I cannot really understand how this works, but
'i'm' could be 'i' (I've seen this in other clues) and 'i' is present in the answer.
'to' could be 'for' and 'for' is found within the answer.
'sound' could be 'play' (playing is a kind of sounding) and 'play' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for play for time that I've seen before include "seek advantage by delaying" , "Delay having to make a decision" , "Seek a temporal advantage" , "Temporise" , "(To) delay in the hope of future advantage" .)
