Etymology
The compound noun 'push-off' is a transparent combination of the verb 'push' and the adverbial particle 'off'. The verb 'push' traces its lineage to Latin pellere, meaning to drive or strike, which evolved through Old French into its current English form denoting the application of force. The particle 'off' is a native English word of Germanic origin, fundamentally meaning separation or movement away. When combined, the literal sense of "pushing oneself away from a surface" provides a clear, logical foundation for its modern meanings, which encompass both the physical act of initiating motion (as in swimming or skating) and the metaphorical moment of departure or commencement of an event.
