Learning

Learning (ラーニング), also known as Learn, is a recurring ability in the series. It is often an ability learned from the Blue Mage class, and allows the user to learn Blue Magic without having to be a Blue Mage.

Final Fantasy V
Learning is a Level 2 Blue Mage ability that requires 20 ABP to learn. If the character is a Mime or Freelancer with Blue Mage mastered, they do not need to equip this ability in order for it to be active, like all other passive abilities aside from Undead and Berserk.

With Learning the player characters learn Blue Magic when being hit by it.

Final Fantasy Tactics Advance
Learning is a Blue Mage ability learned from the Blue Saber for 400 AP.

Final Fantasy Tactics A2: Grimoire of the Rift
Learn is a passive ability learned by the Blue Mage job from the Light Saber weapon for 100 AP. This is also the only ability aside from the basic Black Magic spells and Shieldbearer that can be learned from a piece of equipment available right at the start of the game.
