Definition

Dilation is the process of something widening, expanding, or becoming larger. Think of your pupils dilating in dim light to let in more light. It's often used in medical contexts, like when a doctor dilates your eyes during an exam. Outside medicine, it can describe the widening of a road or the expansion of a concept. Dilation implies an increase in diameter or scope.

Etymology

The word "dilation" comes from the Latin word "dilatare," meaning "to widen or spread out." It combines "dis-" (apart) and "latus" (wide). This Latin root has given rise to other related words like "dilate," which means to widen, and "latitude," which originally referred to width.
