when i speak of teacher of English in general should i use the or a article? Thank you
p.s.:need it for my thesis
It depends on what context you mean for "in general". Here are some general sentences using "the".
"The teacher should correct all mistakes." This could mean "[All] Teachers should correct all mistakes".
"It should be illegal to breed the pit bull terrier". This is not talking about a specific dog.
Simply, perhaps you need "the".
Anyhow, regardless of pit bulls, I was pointing out that the following is a simplistic rule and likely to be wrong in many cases: "If you're speaking in general, use 'a', not 'the'." It's just not realistic. More context is needed to give a useful answer - for example, at least the sentence that the OP wants to use, and the context in which he wants to use it.
