Genie

noun

a spirit of Arabian folklore, as depicted traditionally imprisoned within a bottle or oil lamp, and capable of granting wishes when summoned.

mid 17th century (denoting a guardian or protective spirit): from French génie, from Latin genius (see genius). Génie was adopted in the current sense by the 18th-century French translators of The Arabian Nights' Entertainments, because of its resemblance in form and sense to Arabic jinnī ‘jinnee’.
