IPA: /ɪˈskɛpəmənt/
KK: /ɪˈskɛpəmənt/
A device or mechanism that allows controlled movement, often used in clocks and watches to regulate time by providing energy impulses.
The watchmaker carefully adjusted the escapement to ensure the clock kept accurate time.
Escapement is formed from "escape" (from Old French *escapier*, meaning to flee or get away) and the suffix "-ment" (meaning the action or result of). The word refers to the mechanism that allows for the controlled release of energy, akin to a way of 'fleeing' or 'escaping' from a state of tension.
Think of 'escaping' from tension — the escapement is a mechanism that allows energy to be released in a controlled manner.
