This paper proposes that a family of four related constructions is needed to provide a more complete account for the syntactic and semantic generalizations and idiosyncrasies of the bun1 causative constructions in Hakka by examining the features of CAUSER, CAUSEE, and EFFECT. The traditional claim of semantic entailment as a crucial feature of causation is argued to be too restrictive; pragmatic strengthening is argued to capture the dominant distribution of cause–act functions. In addition, in contrast to what is expected by the prototypical iconic sequencing of the participants in a causal chain, the sequence of a causing event and a resulting event from authentic data is shown to reveal a ground–figure asymmetry. The highlighting of the resulting event for information management is done by linguistic strategies such as topicalization or left-dislocation of CAUSEE and suppression of CAUSER. Such linguistic arrangements are speculated to prepare causative bun1 for undergoing further grammaticalization into the passive function.
