4.5.3. The prediction and the paraphrase of the future perfect form The future perfect form (FuPF) has not only the future of the present perfect form (PrPF) but also the prediction of PrPF. See the following examples. (41) a. You will have already heard the news. b. I will have finished the work by five. (41a) means the speaker thinks s/he heard the news, and (41b) means the speaker might finish it by five. Now, FuPF is formal since "will" or "shall" is co-occurred with the perfect form, that is, a longer form. Therefore, in spoken, only "will" is often used as the paraphrase of FuPF. Moreover, in the time and the condition clauses, even if these mean the future, the present tense is used. This is explained in 1.2.4. It is similar to FuPF. In those clauses, even if they mean FuPF, PrPF is used.
