flawless

the word 'flawless' is a transparent compound formed within middle english. its first element, 'flaw', entered english from old norse flaga, which originally denoted a slab or fragment of stone. this concrete sense naturally evolved to imply a crack or imperfection in the stone, leading to the modern abstract meaning of a defect or blemish. the second element is the native english suffix '-less', from old english -lēas, meaning 'without'. therefore, the literal construction 'without a flaw' directly and logically yields its contemporary meaning of perfect and without defects.

Structure: flaw (defect) + less (without) - flaw: of scandinavian origin (old norse flaga meaning 'slab of stone', later 'fragment', evolving to mean a defect). functions as the core noun root. - less: from old english -lēas, meaning 'devoid of, free from'. functions as a suffix forming adjectives.
