The following sets of forms have certain statable relationships which are most conveniently described in terms of such features as form, process, state, agent, object, and instrument: (1) Form and function: 'horn' of an animal and 'horn' of an instrument for providing sounds. (2) Process and result : 'to run' and 'a run in her stockings'. (3) Process and characteristically associated object: 'to fish' and 'the fish'. (4) State of being and causative of a state: 'foul' (adjective) and 'to foul up the job'. (5) Agent and process: 'the man' and 'to man the ship'. (6) Instrument and process: 'a spear' and 'to spear'. (7) Object and associated characteristic: 'it is a pill' and 'he is a pill'. (8) Form and process: 'a cross' and 'to cross'. It would be quite wrong to assume that all such relationships consist of only two primary relational features, i.e. form and function, process and result, or agent and process.
