Simple and composite sentences

A sentence built around only one grammatical core (predicate) and complete in meaning and intonation is a simple sentence. If two or more simple sentences join in meaning and grammar inside one sentence and are said with one complete intonation, the sentence is composite. The most important feature is predicativity: each part has its own predicate and, usually, its own subject. So counting the predicates in a sentence is the basis for telling simple and composite sentences apart. Homogeneous predicates of one subject, or a converb form (kelib, ochib), do not turn a simple sentence into a composite one because no separate part with its own predicate appears.
