I object to repaired gear going spare (6)
I believe the answer is:
meagre
'going spare' is the definition.
'meagre' can be an answer for 'spare' (thesaurus). I'm not sure about the 'going' bit.
'i object to repaired gear' is the wordplay.
'i object' becomes 'me'.
'to repaired' is an anagram indicator.
'gear' is an anagram of 'agre'.
'me'+'agre'='MEAGRE'
Can you help me to learn more?
(Other definitions for meagre that I've seen before include "skinny" , "Thin -- inadequate" , "'Stingy, skimpy (6)'" , "Scant" , "Scarce, not plentiful" .)
