    Usage notes

    * Expect'' is a mental act and has always a reference to the future, to some coming event; as a person expects to die, or he expects to survive. ''Think]]'' and ''believe'' have reference to the past and present, as well as to the future; as I think the mail has arrived; I believe he came home yesterday, that he is he is at home now. There is a not uncommon use of ''expect'', which is a confusion of the two; as, I expect the mail has arrived; I expect he is at home. This misuse should be avoided. ''[[await, Await'' is a physical or moral act. We await that which, when it comes, will affect us personally. We expect what may, or may not, interest us personally.

    Usage notes
    * (sense) Compare with weaker auxiliary verb (should), indicating a strong probability of the predicate's execution. * (sense) Compare with weaker auxiliary verb (should), indicating mere intent for the predicate's execution; and stronger auxiliary verb (will), indicating that the negative consequence will be unusually severe. * The past tense of "must" is also "must"; however, this usage is almost always literary (see Fritz Leiber quotation above). The past sense is usually conveyed by (had to). It is possible to use (be bound to) for the past also. For this reason, (have to) and (be bound to) are also used as alternatives to (must) in the present and future. * The principal verb, if easily supplied, may be omitted. In modern usage this is mainly literary (see Housman and Tolkien quotations above). * (term) is unusual in its negation. (term) still expresses a definite certainty or requirement, with the predicate negated. (term), on the other hand, is negated in the usual manner. Compare: :: You must not' read that book. (''It '''is''' necessary that you '''not read that book. ) :: You need not' read that book. (''It '''is not necessary that you read that book. ) * The second person singular no longer adds "-est" (as it did in Old English).
