Etymology

The word "stroke" originates from Old English strācian, meaning "to strike lightly," derived from Proto-Germanic straikōną. The root stro- relates to striking or brushing, while the suffix -ke (modern -oke) evolved into a noun-forming ending. Over time, the meaning expanded to include both physical actions (e.g., brushing) and medical conditions (e.g., a "stroke" as a sudden bodily strike). The semantic shift reflects the logic of impact—whether gentle (caress) or severe (medical event).
