I am responding to a thread of posts related to the use of Latin in
spells.

It could be that JKR just likes using Latin as the language of her
spells.  Also, we know that there are more schools than Hogwarts.
Latin, when it was a living language, was used throughout Europe.  Using
Latin for the spells means that witches and wizards throughout Europe
can learn and discuss their craft with each other or learn from a
variety of books without being limited by their native language.
