means The quality of being modest about your own importance, holding an honest and unexaggerated view of yourself.

from From Latin humilis, "low, lowly, on the ground," which grows straight out of humus, "earth" or "soil." So at its root, to be humble is to be down-to-earth in the most literal sense — close to the dirt rather than reaching above it. It came into English through Old French humilité, carrying that grounded, head-bowed posture along with it.
