Officer I once let out for time of voting (7,8)
I believe the answer is:
general election
'voting' is the definition.
(I know that general election is a type of Election\nI know that Election is a type of voting\nTherefore, general election is a type of voting)
'officer i once let out' is the wordplay.
'officer' becomes 'general' (general officer is a kind of officer).
'out' indicates an anagram (out can mean wrong or inaccurate).
'i'+'once'+'let'='ioncelet'
'ioncelet' with letters rearranged gives 'election'.
'general'+'election'='GENERAL ELECTION'
'for time of' acts as a link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for general election that I've seen before include "Poll" , "When all MPs are chosen" , "representative selection" .)
