thank-you
UK: ˈθæŋk juː | US: ˈθæŋk juː
n. an expression of gratitude
adj. expressing gratitude (e.g., a thank-you note)
The phrase "thank you" originates from Old English "þanc" (gratitude) + "ēow" (you, dative/accusative form). Over time, "þanc" evolved into "thank," while "ēow" merged into "you." The hyphenated form "thank-you" emerged in the 18th century as a noun or adjective to describe expressions or gestures of gratitude. The logic reflects a direct address ("you") for the recipient of thanks, solidifying its role in social etiquette.
