Etymology

The word combines "wake" (Old English wacan, meaning "to arise from sleep") and "up" (Old English ūp, denoting completion or direction). Originally literal, it evolved to metaphorical uses (e.g., "wake-up call") in the 19th century, emphasizing abrupt awareness or action. The hyphenated form preserves the phrasal verb structure.
