Small — modest (5)
I believe the answer is:
minor
I believe this is a double definition.
'small' is the first definition.
(I know that small can be written as minor)
'modest' is the second definition.
(I know that modest can be written as minor)
(Other definitions for minor that I've seen before include "Secondary" , "Deceptively realistic (art)" , "Junior" , "Unimportant or unable to vote" , "Of lesser importance" .)
