1. 3.6 Constructions in English
Construction grammar argues that there is no principled divide between lexicon and rules and language is a repertoire of more or less complex pattern---constructions--- that integrate form and meaning in conventionalized and often non-compositional ways.
Form in constructions may refer to any combination of syntactic, morphological or prosodic patterns.
Meaning is understood in a broad sense that includes all we intend to communicate.

2. 3.4 Constructions in English
The constructional view does not assume that certain forms are more “basis” than others, but treats all types of expressions as equally central to capturing grammatical patterning.
