Maybe halve quiet area, the last to go (5)
I believe the answer is:
share
'maybe halve' is the definition.
'share' can be an answer for 'halve' (thesaurus). I'm not sure about the 'maybe' bit.
'quiet area the last to go' is the wordplay.
'quiet' becomes 'sh' (both can be said to tell someone to be quiet).
'the last to go' means to remove the last letter (the last letter goes away).
'area' with its last letter taken away is 'are'.
'sh'+'are'='SHARE'
Can you help me to learn more?
(Other definitions for share that I've seen before include "Portion; plough blade" , "Give portion to others" , "Lot" , "Helping" , "Allotted portion" .)
