La genèse sémantique de la phrase complexe

The initial formation of the complex sentence in French is considered. The synchronic-genetic method is applied, i. e. the classes of language elements are analysed in their deep-semantic sequence. The article treats in detail of the complication of the simple sentence done within the framework of the adverbial modifier which contains an infinitive construction. This type of construction is designated as sub-sentence and the means which introduce it are called connectors. A strictly defined system of three pairs of sub-sentences which represent the initial stage of building real subordinate clauses is worked out.
