slippery

the word 'slippery' originates from the old english adjective slipor, which itself meant 'slippery'. this old english term is related to the verb 'slip', which has germanic roots and is connected to the idea of sliding or gliding smoothly. the suffix -y (here appearing as -ery) is a common english adjectival suffix added to nouns or other roots to denote 'characterized by' or 'full of'. thus, the literal construction 'slip + y' essentially means 'having the quality of being slip-like', a meaning that has remained remarkably consistent from its old english origins to its modern usage describing physical smoothness or metaphorical evasiveness.

Structure: slip + ery slip (from old english slipor meaning 'slippery', functioning as the core root); ery (a variant of the suffix -y, from old english -ig, forming adjectives meaning 'having the quality of')
