Analyze

You choose one object, or creature that you must scan throughout the casting of the spell. The spell can be used to find out the inner workings of any object or creature allowing the user of this spell to figure out things about the object or creature that couldn't be told about the creature through sight. (Things that can be revealed items: properties, effects, spells)

(Things that can be revealed creatures: health, actions, items)

If you analyze spells of others they can be copied down and studied to possibly be used to learn later to learn. (If your DM allows it)
