The aim of following deliberations is presentation the difference between two ways of combining expressions – dependence and co-occurrence. In the first case the junction of syntactic objects is based on the correlation between active requirements of the constitutive component and passive the subordinate element, the subordinate element occupies the syntactic position opened by the parent component. Co-occurrence however is a weaker bond. Secondary element connects to a expression and do not determine its nature nor its complexity. This method of bonding is conditioned by linear position of expressions and prosodic factors.
