 A grammatical phrase is formed when the modes of signifying of its constituent parts are compatible with each other (QPm; QPm-1980: 132). Hence, ‘a man runs’ is a grammatical construction, because the mode of signifying of ‘a man’ (i.e., the mode of the qualified substance) and that of ‘runs’ (i.e., the mode of being performed) are compatible with each other. These modes of signifying are in turn compatible with each other because the modes of being that ‘a man’ and ‘runs’ consignify are compatible with each other.
