The term "lord" originates from an obsolete creature type that is featured as a creature type on numerous older lords although artistically depicted as being of the creature type for which they granted bonuses, these lords were often not of the same creature type. For instance, Lovisa Coldeyes was originally printed as a Human Lord, then changed to a Human Barbarian, and most recently changed to simply a Human. Most "lords" have since had their creature subtypes changed to better reflect the character's race and creature class. The creature type was dropped due to inconsistency between card names and the use of this type, gender issues ( Lady being the correct female form), and so it would not be confused with the so-called "lord" abilities of creatures who grant effects to other creatures according to their creature types, colors, or other attributes. The lords Lord of Atlantis, Zombie Master, and Goblin King, which appeared in Alpha, were the first of several lords, most of which would grant a power/toughness bonus of +1/+1 and an additional bonus, such as a keyword ability (e.g. Due to their support for creature types and appreciably influential impact, lords are often integral to tribal decks.

This is why lord became an informal term for any creature or other permanent which has this ability, even after the creature type was defunct.

Lords conferred boons to other members of the same creature type, usually without conferring such boons to themselves, however. Noble is currently used for the same purpose. Lord is an obsolete creature type for creatures with an occupation of high class or power within a structure or organization.
