Among these may be mentioned the uses of shall and will, should and would, the infinitive and the infinitive clause, conditional sentences, indirect discourse, and the combination of clauses in sentences of different kinds.
The use of tenses is peculiar, as will be seen from the following table of a few common forms of conditional sentences.
In the early period, before the imperfect subjunctive had been shifted to denote present time in conditional sentences (2091), the present subjunctive was used to express action non-occurrent in present time.
The above list will hopefully provide you with a few useful examples demonstrating the appropriate usage of "conditional sentences" in a variety of sentences. We hope that you will now be able to make sentences using this group of words.
