AUX: auxiliary verb
Definition
The only truly auxiliary verb in Russian is быть “to be”. It accompanies the lexical verb of a verb phrase and expresses grammatical distinctions not carried by the lexical verb.
Examples
-
Future tense. Finite future form of быть is combined with infinitive of the lexical verb. The auxiliary expresses person, number and tense: буду делать “I will do”, будешь делать “you will do”, будут делать “they will do”. Note that a limited set of verbs can form future morphologically, without the auxiliary.

Conditional mood. Conditional form (historically aorist) of být is combined with past participle of the lexical verb. The auxiliary expresses person and number, the participle expresses gender and number: сделал бы “I would do.
Masc”, сделала бы “I would do.Fem”, сделали бы “we would do.Masc”. -
Passive voice. A form of быть (in various tenses and moods or in the infinitive) is combined with passive participle of the lexical verb. The auxiliary expresses person, number, tense(past and future) and mood, the participle expresses gender, number and voice: будет сделан “he will be done”, был сделан “he was done”, был бы сделан “he would be done”,
Modal verbs are not auxiliaries
Russian modal verbs are not considered auxiliary and they are tagged VERB.
Their behavior is only slightly different from other content verbs.
