I think there's a confusion on how to say the types, so I hope this blog helps you out with that. I found the sayings in Pokémon X and Pokémon Y, so they're officially correct.
- If you want to say only the type without referring to Pokémon, moves or others, just say "(type) type".
- Now, if you want to refer about a Pokémon, for example, add a -, like this "(type)-type Pokémon".
- For example, the in-game description of Flower Shield is: The user raises the Defense stat of all Grass-type Pokémon in battle with a mysterious power.
- If you want to say two types at the same time, you don't need to repeat, just say "(type) and (type) type", without referring to anything precise, just the types.
- You can check the description for Flying Press, it is: The user dives down onto the target from the sky. This move is Fighting and Flying type simultaneously.
- By the other side, to refer to moves, attacks or even Pokémon of two or more different types, write it this way "(type)- and (type)-type attacks".
- For example, the description for Foresight shows us how it's said: Enables a Ghost-type target to be hit with Normal- and Fighting-type attacks. This also enables an evasive target to be hit.
- You can also refer to the Pokémon by just saying "(type) types".
- Now check the description for Freeze-Dry, it is The user rapidly cools the target. This may also leave the target frozen. This move is super effective on Water types.
- For several Pokémon and without saying "Pokémon", use something like this "(type), (type), and (type) types".
- The description for Sandstorm is an example, A five-turn sandstorm is summoned to hurt all combatants except the Rock, Ground, and Steel types.
- To avoid repeating time after time the word "type", you can just say something like this "(bla bla bla)'s type to (type)".
- Okay, maybe the description for this one was a little confusing, so take a look at the description for Soak: The user shoots a torrent of water at the target and changes the target's type to Water.
- There are many things that you can "add a type", for example:
- Moves
- Pokémon
- Gym Leaders
- Combatants
- Attacks
- Trainers
- These are some things that we can't say that they have a type:
- Abilities
- Weathers
- People
- Status conditions
- Evolutions
- Megaevolutions
- Berries
- Places
- Etc.
Ok, so I think that's all I have to say about. I hope this blog helped you to know how to say things referring to the elemental types. If I just missed something or if you have a question about, please comment and I will answer your question as fast as I can. Thanks for reading.
