This document discusses how clauses represent experience through three metafunctional lines of meaning: experiential, interpersonal, and textual. It explains how clauses construe relationships between elements through processes like signification. There are different types of processes that provide schemas for construing domains of experience, including material, mental, verbal, existential, relational, and behavioral processes. An example shows how a clause represents the relationship between the token "usually" and its value "mostly" through the process "means".
