blinking

The verb 'blink' has a complex Germanic origin, likely related to words meaning to gleam, deceive, or flinch, all involving a sudden, quick movement. The core concept evolved to specifically mean the rapid closing and opening of the eyelids. Adding the present participle suffix '-ing' creates an adjective describing something that performs this action, like a 'blinking light'. In British English slang, this literal sense of repetitive, noticeable action was semantically extended to function as a mild intensifier, replacing stronger expletives, thus giving us the emphatic use in phrases like 'a blinking miracle'.

Structure: blink (to shut and open the eyes quickly) + ing (adjective-forming suffix) 'Blink' is of Middle English origin, likely from a blend of earlier words like 'blenchen' (to move suddenly) and Old English 'blincan' (to deceive, shut the eyes). The '-ing' suffix is from Old English '-ende', a present participle ending used to form adjectives.
