Staying with one offer in gold initially (7)
I believe the answer is:
abiding
'staying' is the definition.
('abide' can be a synonym of 'stay')
'one offer in gold initially' is the wordplay.
'one' becomes 'a' (a thing is one thing).
'offer' becomes 'bid' (synonyms).
'initially' indicates taking the first letters.
The initial letter of 'gold' is 'g'.
'a'+'bid'+'in'+'g'='ABIDING'
'with' acts as a link.
(Other definitions for abiding that I've seen before include "With a lasting quality" , "Durable, lasting" , "Permanent" , "standing" , "Remaining or residing" .)
