Other forms: residing, resided, resides
To reside is the formal word for to live in a place. Reside in London, currently residing at, where they reside.
It belongs to forms, legal documents and official letters, where live would be too plain — and using it in speech sounds stiff or comic. It also means to be located in something abstract: the power resides with Parliament, the fault resides in the design. Note residence, resident, residency; and that the Latin means to sit back or remain behind.
