Perhaps he could speak Latin. Latin is often associated with magic in many fictional universes, including the Harry Potter universe. It's possible that instead of English, he has a deep understanding of Latin for casting spells and studying ancient magic texts. For example, many spells in the real Potter series have Latin roots, so in this fanfiction, he might directly use Latin in his daily magic use.
The relationship with the wider wizarding community would change. In the wizarding world outside of Hogwarts, Harry's lack of English would be a significant factor. When dealing with the Ministry of Magic, he would need interpreters or have to learn some form of magical sign language. His fame as 'The Boy Who Lived' might be affected as well. People might not understand his story as easily, and he might have to find new ways to connect with the public. This could lead to a more isolated Harry, or it could open up new opportunities for him to form unique relationships with those who can communicate with him in his non - English language.
Yes, it is possible. Fanfiction often takes creative liberties. Writers might choose to have Harry Potter speak only Latin for various reasons. Maybe they want to explore a different aspect of his magical education, as Latin is often associated with magic in the wizarding world. It could also be a way to make the story more unique or to tie in with some ancient magic plotline.
One implication could be communication problems. His friends might not understand him, leading to some comical or tense situations. For instance, Ron might be completely lost when Harry tries to tell him something important. Also, it could change his relationship with his teachers. If he can only speak Latin, some teachers might be more interested in him, thinking he has a special connection to ancient magic.
Well, in some versions of this fanfiction, Harry might discover it by accident. For example, he could be in a situation where he's near a dragon and instead of the usual fear or aggression from the dragon, it seems to be communicating with him in a strange way. Maybe the dragon's eyes seem to be trying to convey a message, and Harry just somehow understands it, like he has an innate sense that he can pick up on the dragon's thoughts.
The story would likely become more exciting. Harry could use the dragons as allies. For instance, he could ride a dragon to quickly reach places he needs to be. It would also add an element of mystery as he discovers more about the dragons' language and culture.
He could have adventures like helping magical animals solve their disputes. For example, he might mediate between a group of bowtruckles and a family of unicorns over territory. He could also use his ability to communicate with animals to gather information about dark wizards who are hiding in the Forbidden Forest, as the animals would be able to tell him if they've seen any suspicious activity.
Well, it could be about Harry Potter having the characteristics or powers of Revan. Maybe Harry discovers some ancient magic that is similar to what Revan had in the Star Wars universe. It could also involve a plot where the Hogwarts world is threatened in a way that requires Harry to use Revan - like skills to save it.
It could entail Harry having the powers of a dovahkiin. So he might be able to shout like a dragon and have enhanced physical abilities. He could use these powers to fight Voldemort in a completely different way, perhaps using dragon shouts to disarm or stun death eaters.
It could be about how the wizarding world responds to the muggle tragedy. Maybe they send help secretly or use magic to prevent similar disasters in the future.
Potentially, it could be about Harry's destiny as a guardian of the balance between the magical and non - magical worlds. He might discover that he has a role to play in preventing the two worlds from colliding in a disastrous way. So he has to take on this new identity as a guardian, which involves making difficult choices, facing new challenges, and forging new relationships with both wizards and non - wizards.
