Definition of concavity

concavitynoun

độ lõm

/kɒnˈkævəti//kɑːnˈkævəti/

"Concavity" derives from the Latin word "concavus," meaning "hollow" or "curved inwards." This root is further broken down into "con-" meaning "with" or "together" and "cavus" meaning "hollow." The "con-" prefix highlights the "togetherness" of the inward curve, implying a shape that curves inwards as a unified whole. Hence, "concavity" describes the property of a surface curving inward, like the inside of a bowl.
