'stay-at-home' originates from the English phrase 'stay at home,' where 'stay' meant 'to remain' and 'home' referred to one's place of residence.

The phrase 'stay at home' has been used in English since the 19th century to describe someone who remains at home, especially for domestic duties.

Initially, it meant 'to remain at one's residence,' but over time it evolved to specifically describe someone who stays home for domestic responsibilities.
