slippage

the word 'slippage' is a modern english formation that combines the germanic root 'slip' with the french-derived nominal suffix '-age'. the verb 'slip' originates from middle english, evolving from old english and proto-germanic roots conveying the sense of smooth, unintended motion. the suffix '-age', entering english via old french from latin '-aticum', is used to form nouns denoting an action, its result, or a collective function. thus, 'slippage' literally means "the process or result of slipping," a meaning which has extended metaphorically from physical sliding to describe failures in meeting abstract standards or deadlines.

Structure: slip (to slide) + page (noun suffix) slip (from middle english 'slippen', of old english/germanic origin, meaning to slide or glide smoothly). page (a variant of the noun-forming suffix '-age', from old french, from latin '-aticum', indicating an action, process, or result).
