The present paper deals with the questions connected with the verb marks in an infinitive nominalization, factitive and infinitive transformation. In the process of nominalization the marks designating the tense of a verb are lost and an infinitive is translated according to the tense of the predicate of a basic sentence. There is a difference between a simple segment and a verbal group. This difference is either complete or incomplete. An afore-mentioned difference is clearly seen when we compare an infinitive nominalization and different clauses on which it is based. Some syntagmas expressing a complete action make it possible to distinguish between the relative pronouns expressing simultaneity and coordination. The relationship between an infinitive and the initial tense is comparatively simple when the infinitive is formed by means of the nominalization of the sentence which is based on "Que". In case when the verbs are accompanied with pronoun transformation, i.e. when they represent the pronoun verbs, we can state that by means of an infinitive nominalization a passive verb is represented. In case, when the infinitive (expressing either active or passive form) is not accompanied by the subject, a kind of misunderstanding can be caused. We have to distinguish between the factitive transformation of the pronoun verbs and the combination of reflexive and factitive transformations.
