One-member sentences

A two-member sentence has both a subject and a predicate; a one-member sentence has only one main part, and the other is absent and the meaning does not require it. There are four kinds of one-member sentences: «назывные» (nominative), «определённо-личные» (definite-personal), «неопределённо-личные» (indefinite-personal) and «безличные» (impersonal). In a nominative sentence the main part is a noun in the nominative acting as the subject: «Раннее утро. Туман над рекой.» Such sentences state that something exists and quickly paint pictures of nature or a stage setting; they may be extended or unextended. In a definite-personal sentence the main part is a predicate: a verb in the 1st or 2nd person of the present or future, or in the imperative: «Жду тебя у фонтана», «Передайте, пожалуйста, соль». The personal ending makes it clear who acts, so the pronoun «я, ты, мы, вы» need not be added. These sentences are common in speech and literary texts because they avoid repeating the pronoun.
