9.3.2. The main differences between the Compound and Complex sentences.

CRITERIA	COMPLEX	COMPOUND
structure	Main clause // subordinate clause, connected syndentically	Independent clauses. connected either syndentically or asyndentically
Types of construction	hypotaxis (subordination)	parataxis (coordination)
Types of clause connection	syndetic(subordinate conjunctions, connective words, conjunctive adverbs) A conjunction serves as a formal element connecting separate clauses. A connective serves as a connecting link and has at the same time a syntactic function in the subordinate clause it introduces.	syndetic(coordinative conjunctions, conjunctive adverbs) asyndetic
the degree of the predicative explicitness(composite sentences)	Of complete composition (complex) of concise composition (semi-complex)	Of complete composition (compound) of concise composition (semi- compound)

9.4. The semi-compound and the semi complex sentences.

9.4.1. Semi-complex sentence

The semi-composite sentence is to be defined as a sentence with more than one predicative lines which are expressed in fusion. For the most part, one of these lines can be identified as the leading or dominant, the others making the semi-predicative expansion of the sentence. The expanding semi-predicative line in the minimal semi-composite sentence is either wholly fused with the dominant (complete) predicative line of the construction, or partially fused with it, being weakened as a result of the fusing derivational transformation.

The semi-composite sentence displays an intermediary syntactic character between the composite sentence and the simple sentence. Its immediate syntagmatic structure ("surface" structure) is analogous to that of an expanded simple sentence, since it possesses only one completely expressed predicative unit. Its derivational structure ("deep" structure), on the other hand, is analogous to that of a composite sentence, because it is derived from two or more completely predicative units — its base sentences.

9.4.2.VSemi-compound sentence

The semi-compound sentence is a semi-composite sentence built up on the principle of coordination. Proceeding from the outlined grammatical analysis of the composite sentence, the structure of the semi-compound sentence is derivationally to be traced back to minimum two base sentences having an identical element belonging to one or both of their principal syntactic positions, i.e. either the subject, or the predicate, or both. By the process of semi-compounding, the sentences overlap round the identical element sharing it in coordinative fusion, which can be either syndetic or asyndetic. Thus, from the formal point of view, a sentence possessing coordinated notional parts of immediately sentential reference (directly related to its predicative line) is to be treated as semi-compound. But different structural types of syntactic coordination even of direct sentential reference (coordinated subjects, predicates, objects, adverbial modifiers) display very different implications as regards semi-compounding composition of sentences.
