a strategy in which a noncausal event and its counterpart causal event are expressed by forms of equal morphological structure. Example: in German, the causal event predicate aufwechen 'wake (someone) up' and the noncausal event predicate aufwachen 'wake up' are expressed by morphologically related forms, but neither form is morphologically more complex than the other. In English, the suppletive causal event predicate kill vs. noncausal event predicate die are also analyzed as instances of the equipollent strategy. The term 'equipollent' is used for the same strategy in other constructions as well. (Section 6.3.4)
