Learning represents your character's general book-smarts. Your character would theoretically gain more skill points when leveling if your Learning is higher, but this has been unimplemented.
Learning also plays a minor role in determining MP, but because every point of Learning is worth less than 1/6th of what a point of Magic is worth, Learning is the prime attribute of only one spell, and there is no known link between high Learning and an improvement in any of the Learning-related skills, Learning one of the least useful attributes to train.
If you have money the fastest way to improve Learning is to buy slaves or horses and genetically engineer pets over and over. Otherwise the fastest way to improve Learning is to eat Food that improves Learning (especially vegetables and higher-ranked fish) or use Literacy to read Books of any sort besides possibly skill books. (Skill books will only train Learning if they are skill books about learning-related skills.)
Learning has many practical non-combat skills associated with it. Because Gardening and Cooking both raise learning, and vegetables are the most common type of food grown at a farm, learning both those skills and cooking vegetables you raise yourself can be a good way to increase Learning.
If your Learning increases, you will get the message "You feel studious."
If your Learning decreases, you will get the message "You lose curiosity."
As of Elona+, Alchemy (and therefore Learning) is trained by drinking potions, hitting enemies with them, or walking on puddles. It does not appear to affect the duration or strength of potions. Gene Engineering and Gardening (and therefore Learning) are trained by searching at specific gathering spots.
