Dame
Dame is a traditionally British honorific title given to women who have been admitted to certain orders of chivalry. It is the female equivalent of Sir, the title used by knights. Baronetesses in their own right also use the title Dame.
A woman appointed to the grades of Dame Commander or Dame Grand Cross of the Order of Saint John, the Order of the Holy Sepulchre, the Order of the Bath, the Order of Saint Michael and Saint George, the Royal Victorian Order, or the Order of the British Empire becomes a dame. A Central European order in which female members receive the rank of Dame is the Order of Saint George. Since there is no female equivalent to a Knight Bachelor, women are always appointed to an order of chivalry. Women who are appointed to the Order of the Garter or the Order of the Thistle are given the title of Lady rather than Dame.
Women receive all their honours in the same fashion as men receiving decorations or medals, even if they are receiving a damehood, so there is no female word equivalent of being "knighted".
