Alternation ‘Reflexive derivation’ (Coded)

Reflexive is marked by the derivational suffix -mei. In addition to marking a valency alternation, this suffix is often applied without a valency change but with a semantic change in which the agency of the subject is downgraded; the resulting verb is translated by native speakers as 'do x poorly'. If this is the only reading of the verb derived with -mei, then it is counted as not participating in the reflexive derivation.
