Secure option to provide state of balance (12)
I believe the answer is:
counterpoise
'state of balance' is the definition.
'counterpoise' can be an answer for 'balance' (synonyms). I'm not certain of the 'state of' bit.
'secure option to provide' is the wordplay.
'to provide' indicates an anagram.
'secure'+'option'='secureoption'
'secureoption' anagrammed gives 'COUNTERPOISE'.
Can you help me to learn more?
(Other definitions for counterpoise that I've seen before include "Weight balancing another" , "balance" , "Balancing factor" , "Offset" .)
