Modest, meek (6)
I believe the answer is:
humble
I believe this is a double definition.
'modest' is the first definition.
(I know that modest can be written as humble)
'meek' is the second definition.
(similar in meaning)
(Other definitions for humble that I've seen before include "Self-effacing" , "Servile" , "Not proud or pretentious" , "Lowly - modest - unpretentious" , "Eat - - pie" .)
