1. TMs and HMs:
* TMs (Technical Machines): Reusable items that teach a Pokémon a specific move. You can find them in various locations, purchase them, or receive them as rewards.
* HMs (Hidden Machines): Similar to TMs, but they teach moves that are primarily used for navigating the environment, like cutting down trees or pushing boulders.
2. Move Tutor:
* Move Tutor: A special NPC who can teach Pokémon moves they haven't learned through other means. You often need to use special items or pay a fee to unlock this service.
3. Breeding:
* Egg Moves: Some moves can be passed down from parents to their offspring through breeding. Not all moves can be inherited, but some are specific to certain Pokémon lines.
4. Level-Up:
* Level-Up: Some Pokémon can learn old moves as they level up, especially if they have access to multiple move pools. It's not always guaranteed, but it's possible.
5. Evolution:
* Evolution: Some Pokémon learn old moves as they evolve. This can be a way to access moves that might not be available through other methods.
Important Note:
* Generation 6 and beyond: The "Move Tutor" system was removed, but "TMs" and "HMs" are still widely available. You can also use "Breeding" to unlock certain moves for your Pokémon.
To know which moves a Pokémon can learn and how to unlock them, you can use a Pokémon guide, a Pokédex, or consult online resources.
