Functional Sentence Pespective (FSP)

between the Grammatical Sentence Pattern(GSP). the Semantic Sentence Pattern(SSP), and the Communicative Sentence Pattern(CSP)

e.g. John was written a poem.

SSP: Agent-Action-Goal

GSP: Subject-Verb-Object

CSP: Theme-Transition-Rheme

there is a distinction between sentence and utterence.
