Figure a hush to be something you can hear! (5)
I believe the answer is:
clash
'can hear' is the definition.
I can't tell whether this defines the answer.
'figure a hush to be something' is the wordplay.
'figure' becomes 'c' (I've seen this in other clues).
'a hush' becomes 'sh' (both are used to tell someone to be quiet).
'to' is a charade indicator (letters next to each other) (I've seen this in other clues).
'be something' becomes 'la' (I can't justify this - if you can you should give a lot more credence to this answer).
'sh' put after 'la' is 'lash'.
'c'+'lash'='CLASH'
'you' acts as a link.
Can you help me to learn more?
(Other definitions for clash that I've seen before include "Forceful disagreement" , "jar" , "Loud noise - conflict" , "Conflict, discord" , "Come into violent conflict" .)
