Proportions surrounding fish (6)
I believe the answer is:
scales
This could be a double definition.
'proportions' is the first definition.
(I know this)
'surrounding fish' is the second definition.
Although both the answer and 'fish' are verbs, they are not in the same form of the verb. However, I know that 'fish' relates to this answer.
Can you help me to learn more?
(Other definitions for scales that I've seen before include "Removes plaque" , "Weighting machines - Sign of Libra" , "Balance - climbs" , "though it's not Pisces" , "Sets of musical notes - balanced on a fish?" .)
