Making pivot erratically, suppresses person who put them in office (5)
I believe the answer is:
voter
'person who put them in office' is the definition.
'voter' can be an answer for 'person' (voter is a kind of person). I'm not sure about the remainder of the definition.
'making pivot erratically suppresses' is the wordplay.
'suppresses' indicates the answer is hidden within the clue (the clue suppresses or covers up the answer).
'VOTER' is hidden within 'making pivot erratically'.
Can you help me to learn more?
(Other definitions for voter that I've seen before include "Cross writer" , "Lively dances (esp. Irish)" , "One participating in ballot" , "One exercising the ballot" , "Election participant" .)
