means The quality of being humble, unassuming, or restrained about one's abilities, achievements, or body.

from From Latin modestus, 'keeping within measure,' built on modus, 'measure' or 'limit' — the same root that gives us 'mode,' 'modify,' and 'moderate.' The idea was literally about staying within proper bounds; modesty was once a sibling of measurement before it became a matter of manners. It entered English in the 16th century by way of French modestie.
