lady

lady, in the British Isles, a general title for any peeress below the rank of duchess and also for the wife of a baronet or of a knight. Before the Hanoverian succession, when the use of “princess” became settled practice, royal daughters were styled Lady Forename or the Lady Forename. “Lady” is ordinarily used as a less formal alternative to the full title of a countess, viscountess, or baroness; where the name is territorial, the “of ” is dropped—thus the Vicountess of A. but Lady A. The daughters of dukes, marquesses, and earls also have, by courtesy, the title of lady prefixed to their forename and surname—e.g., Lady Jane Grey.
