Predication (SR3) – syntagmatic relations of interdependence. Predication may be of two kinds – primary (sentence level) and secondary (phrase level). Primary predication is observed between the subject and the predicate of the sentence while secondary predication is observed between non-finite forms of the verb and nominal elements within the sentence. Secondary predication serves the basis for gerundial, infinitive and participial word-groups (predicative complexes).
Syntactic function is the function of a unit on the basis of which it is included to a larger unit: in the word-group a smart student the word ‘smart’ is in subordinate attributive relations to the head element. In traditional terms it is used to denote syntactic function of a unit within the sentence (subject, predicate, etc.).
