Typological Information
Western Micronesian language rightwards derivational reduplication seems to be a feature of all nuclear Micronesian languages (cf. Harrison 1973: 438).
Byrd (1993) explains the two patterns of final reduplication (i.e. -CVC and -V:C) as the result of one single process: "bimoraic syllable reduplication", which seems to be a rather unusual type of reduplication. Here -CVC subsumes both forms, as the variation is conditioned by the form of the simplex.
Productivity
rightwards reduplication is productive (only restrictions by semantic compatibility)
