Question: d&d can wizards learn healing spells?
Answer: Wizards and Sorcerers don't typically have access to healing spells, for example, and adding a healing spell to the wizard class list would step on the cleric's turf. So, if you want to use healing spells, go for any of the classes with those in their spell list: Bard, Druid, Ranger, Paladin, Cleric.
