The Composite Sentence as a unit of syntax

function. Means of clause connection

polypredicative construction.
It is a structural, semantic and functional unity of

two or more subject-predicate structures (Bloch).

A LINGUISTIC SIGN

meaning

form

function

reflects two or more situational events.
It expresses a complex act

of thought -- an act of mental activity, which falls into two or more closely combined intellectual efforts.
It reflect two or more situational events, which form a unity.

more subject-predicate constructions (predicative lines → clauses).
A clause corresponds to

a separate simple sentence.
E.g. He was wearing pyjamas when he came up into the square, but there was nobody to see him. Cf. He was wearing pyjamas. He came up into the square. There was nobody to see him.

no (coherently presented) situational unity

to inform of a certain complex situation. (The sequence of

simple sentences expresses the events in their natural temporal succession.)

and adverbs (who, what, where)
conjunctive phraseological units (so...that, hardly...when)
* Conjunctions

do not function as members of a sentence, while conjunctive words do.
Conjunctions are used both in complex and compound sentences, while conjunctive words -- only in complex ones.
Conj. and conj. words can introduce not only subordinate clauses, but also conjunctive phrases: when in Moscow.
The boundary b/w syndetic and asyndetic joining is not clear sometimes. E.g. Tom studied a lot, yet he didn't pass the test. Yet -- a conjunction, an adverb? (Ilyish)

he would…, I know who he is)
tense, phase, mood forms

(If he comes...)
intonation
Asyndetic composite sentences, which consist of similar parts, may have the meaning of enumeration, comparison; of the parts of different type -- more complex semantic relations (in this case intonation is a means of connection).
