dilator

The word 'dilator' is built upon the Latin verb dilatare, meaning "to spread out, expand, or widen." This verb itself is a composite of the prefix dis- (apart, widely) and the root from lātus, the past participle of ferre (to bear or carry). The literal image is of "carrying something apart," which evolved into the abstract sense of causing expansion or widening. In medical terminology, the agent suffix -or was appended to form a noun identifying an instrument, muscle, or substance that performs the specific action of dilation, thus completing the journey from the ancient concept of spatial expansion to a precise modern medical tool or agent.
