When we are talking about Russian grammar  especially verbs, we will find that one infinitive verb may consisted of conjugations with subjects and which you could see about related information further in conjugation in Russian language, the aspect whether it’s in perfective or imperfective, Russian tenses (past, present or future), with or without prefixes and others. In addition, the verb may be preceded by a prefix and or followed by suffix. A prefix normally adds some element of meaning to the initial verb (and may change its aspect), for example, when added to the verb читать (to read), the prefix пере– has the meaning re- and produces the new (perspective) verb, перечитать (to re-read).
