So a "tutor" who fits in that category? In the US it would be
someone you hired on the side to help you better understand the
course material. Thus the confusion.
Here (UK) a tutor could be privately hired, or could be a person
appointed to oversee the studies of a group of students (a university
tutor often does that, and may also be concerned with the wellbeing of
the students in other ways), or in general is anyone who teaches (in
particular, a person who teaches a specific subject).
The usage has changed over time, and in different social classes (rich
people 50 or so years ago often were taught at home by tutors hired by
the parents, I suspect that the US usage has kept that sort of meaning),
whereas at some schools all of the teachers are known as 'tutors'.
