The word "lookout" is a compound formed from the verb "look" (Old English lōcian, meaning "to see or observe") and the adverb/preposition "out" (Old English ūt, meaning "away from the inside"). It emerged in the 17th century, originally describing a physical vantage point for observation (e.g., on ships or towers). Over time, it extended metaphorically to refer to the act of vigilance itself. The morphemes retain their original meanings, combining logically to convey "watching outward."
