Under the causativization approach, he proposes a set tions alone suggest that the common base approach must be taken to account for equipollent alternations, as in (2)a-(2)j, which involve overt affixes for both the causative and the inchoative alternants.
the same line of reasoning also suggests that causativization of inchoative verbs and anticausativization of causative verbs may be involved in (2)k-(2)m and (2)n-(2)o, respectively.
