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.
