TM and HM

TM stands for Technical Machine. A Technical Machine in the Pokémon Universe is in the form of a CD. Pokemon Trainers can give these CDs to their Pokémon to help them to learn new moves to use against opponent Pokémon. In Pokemon generations 1-4, TM's coukd only be used once, and then they disappear.Recently, though, Black and White allowed players to use them more than once, just like an HM.
