escal <climb (from Latin *scala*) + ator<noun suffix indicating an agent or device>
Etymology

The word escalator originates from the Latin scala (meaning "ladder" or "staircase"), combined with the suffix -ator (denoting a tool or device). It was trademarked in 1900 by the Otis Elevator Company for their moving staircase invention. Over time, the term became genericized, losing its trademark status. The morpheme escal- reflects the climbing action, while -ator marks it as a mechanical device.
