Student or Learner
Is my doctor/professor or teacher a common phrase among students in developed countries such as Britain, USA, Canada, Australia, and others?
To me, I would say a teacher whom I take class with or a teacher who teaches us/me in English, for example. Do you have a set phrase when you refer to someone who gives you a formal/regular or an informal class, please? What should we say here?
There is NO sense that the teacher belongs to you or that you are the only person taught by that teacher, if that's what you're worried about.
If I said "My doctor suggested I lose weight" I simply mean "the doctor that I visit" not "my personal doctor, whom no one else sees."
"A teacher who teaches us" is very unnatural compared to "My teacher."
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
In addition, you can add a subject (a topic, not the grammatical term) to the teacher construction. You don't need to say "The teacher who teaches me English" or "My teacher who teaches me English", just "my English teacher".
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
