Syntactic coordination and subordination is built by combining predicates in the superordinate moods (indicative, interrogative, imperative and optative) with predicates in the subordinate moods (conditional, causative, contemporative and participial). The contemporative has both coordinative and subordinative functions, depending on the context.Fortescue(1984) p. 34 The relative order of the main clause and its coordinate or subordinate clauses is relatively free and is subject mostly to pragmatic concerns.Fortescue (1993) p. 270
