Урок 26. Сослагательное наклонение. Lesson 26. The subjunctive mood.

As well as forming the conditional mood, the past tense of the verb + the particle бы renders the subjunctive in Russian. There are no sets of distinctive verbal endings or different subjunctive tenses of the sort found in, for example, French, Italian and Spanish. As in these Western European languages, though, the subjunctive in Russian is used in concessive clauses and in subordinate clauses after verbs of wishing. It may also be used,  in subordinate clauses after verbs of ordering, permitting, fearing and doubting and after various negative antecedents.

Урок 24. Условное наклонение. Lesson 24. The conditional mood (smth will/will not happen or smth might happen).

Conditional sentences in Russian are of two types, depending on whether the speaker means that in certain circumstances (a) smth will/will not happen or (b) sth might happen. Usage in the two clauses of a conditional sentence (i.e. the subordinate clause which contains the condition, usually introduced by eсли, if, and the main clause, which states the consequence) differs in the two types of conditional sentence.

Note: in both types of conditional sentence the clause stating the consequence may be introduced by то or тогдa (then), provided that it follows the clause containing the condition.
