Attach

Attach is a keyword action. It means "to move an Aura, Equipment, or Fortification onto another object or player".
==History==
Attach was first used in Mirrodin to allow Equipment to target creatures when being "put on a card." In trying to clean up Auras in Ninth Edition, it was important for enchantments to also have a word so it was decided by R&D to let Auras use the same word Equipment used instead of "move". 
Blue is the primary color of moving attached things.
Future Sight added the Fortification subtype which could be attached to a Land. That artifact type was not printed on another card until 2024, when a single Fortification card was printed in Fallout, bringing the total number of Fortifications up to two.
The opposite of attach, "unattach", has been used in various contexts, as a cost, a keyword action, and an equipment's state.
