Which one is correct? "A teacher of English" or "An English teacher"? [closed]

I want to know which is correct

• teacher of English

or

• English teacher.

If you put the accent on the word "teacher", then it means "a teacher from England." If you put the accent on the word "English", then it means "a teacher who teaches English".

Or in another way, if you say "a teacher of English", then it means a teacher who teaches English. If you want to say a teacher who comes from England, then a clearer way would be "a teacher from England."

Very slight difference in meaning here:

"Teacher of English" can refer to anyone who is teaching English, to anyone.

"English Teacher" has the connotation that it is someone who is in the Education system, is paid, and has a class of students to teach to.

I.e.:

John is a teacher of English. He is just really good with English, so he can instruct basically anyone.

Jane is an English teacher. She works at my school.

Both are grammatically correct, and which one to use will depend on the context.

teacher of English: This makes an explicit reference to the subject. It doesn't matter if the teacher is from England or not, it just cares about the fact that the teacher teaches English.

Examples where teacher of English is used:

http://www.teacher-of-english.com/
http://inspiringenglishteacher.sg/ (its funny to see here how the award is for Teachers of English but the URL is a contraction of "Inspiring English Teacher")

English teacher: This can be ambiguous depending on the context because English can relate to nationality or to the subject English. If such an ambiguity is not possible in your context, English teacher is shorter, easier to pronounce and the natural choice of words. It would even sound a little awkward if you, at your own school, should refer to your English teacher as your teacher of English.

Examples where English teacher is used:

Either can be correct if used in the proper context:

Case #1

"I am a teacher of English. Teaching the language is my profession and I am current unemployed."

Case #2

"I am an English teacher. Teaching the English language is my job at Linwood School."

Case #3

"I am an English teacher. My nationality is English and I have a position as Instructor of Anatomy at the University of Warwick."

If the context is Case #3, I recommend removing the first sentence completely to avoid confusion.
