Student or Learner
"Teachers who lack knowledge either in the micro or the macro fields of Linguistics will only be able to tell what the students should not say, whereas I will also be able to tell them why they should not say it and whether they may actually say it in certain contexts."
1- Is this sentence grammatically correct?
2- May I omit the definite article "the" before the word "macro" in this sentence?
Thank you for your reply in advance.
Thank you, emsr2d2. What would you say about putting "the" before "students"?
