at-home

The compound adjective "at-home" is a straightforward combination of two native English elements. The preposition "at," from Old English æt, denotes a state or location, while "home," from Old English hām, signifies a dwelling or place of belonging. The phrase "at home" was used adverbially for centuries before solidifying into a hyphenated adjective in the 18th century to describe events, services, or a feeling associated with the domestic sphere. Its logic is transparent: something that is "at-home" possesses the qualities or occurs in the context of the home environment.
