a strategy for expressing the categories of subject (S), verb (V), and object (O) in a transitive construction, and subject in an intransitive construction. Some linguists use A and P instead of S and O, respectively, in describing the basic word order of transitive constructions. Basic word order is distinguished from nonbasic word orders in terms of information packaging (basic word order represents topic–comment information packaging); less structural coding; and higher token frequency. Example: the basic word order of English is SVO, as in Jerry saw the bluebird on Sunday. Some linguists analyze basic word order in terms of the pair of binary orders subject–verb and object–verb. Sometimes the order of oblique phrases is included; if so, the oblique phrase is abbreviated X; English is SVOX. (Section 6.2.2)
