Related to The word"be"
Dear sir,Yesterday I asked a question about the word 'be'. But I am not satisfied with one answer that says 'Is your dictionary broken? I think it is a joke and is amazing. I would like to say My dictionary has no defect.He may not understood my question! May I repeat the question,'Is there meaning it'self (only) the word "be"? Like other words, get, take,put. We can see in dictionary meaning of 'be'-live,exist,remain. I think it has meaning itself.Ex."you must be at the police station tomorrow".In this sentence 'be'has strong meaning ,that present of the person is must. One educated man told me that' be' has no any meaning itself (only).I want know which is true? I would like to say an important that,as I am leaner of english,I am expecting your answers should be from experts of english not from any member like student and I want show your answer to that person as an evidence. Thanks.
