Syntactic form may be described as the distributional formula of the unit (pattern). John hits the ball – N1 + V + N2.
Transformational syntax states that the combination of phrase structure grammar and transformational grammar must be able to generate all expressions that are part of the language.
Subordination (SR2) – syntagmatic relations of dependence. SR2 are established between the constituents of different linguistic rank. They are observed on the phrase and sentence level. Subordination may be of three different kinds – adverbial (to speak slowly), objective (to see a house) and attributive (a beautiful flower). Forms of subordination may also be different – agreement (this book – these books), government (help us), adjournment (the use of modifying particles just, only, even, etc.) and enclosure (the use of modal words and their equivalents really, after all, etc.).
