Morphology
The compound is compositionally built from 'escape' (release) + 'wheel' (rotating object), so a learner could guess it is a wheel related to an escaping or release function. However, the precise horological sense — a toothed gear that engages the escapement to regulate movement — is technical and not directly predictable from the common senses of the constituents. Therefore it offers a clear clue but requires specialised knowledge, making it only partially transparent to a B1 learner.
Etymology
Escape wheel comes from old clocks: the small toothed wheel was allowed to escape one tooth at a time past a little lever, like a gate letting people through slowly. That's why the name means the clock part that helps 'control' the movement and 'keep time'.
