'via' is often used in formal contexts, especially in written communication. It's not typically used to describe everyday routes or methods. For instance, one wouldn't usually say, 'I went to the kitchen via the living room,' even if it's technically correct. Ensure clarity when using 'via' to avoid ambiguity. For instance, 'I heard it via John' could mean John told you directly, or you heard it from someone else who heard it from John.
