Frances Karttunen: 

NEPANŌ-TL mutuality, reciprocity / unos a otros, o unos con otros, o los unos a los otros (M) [(5)Cf.35v,125r]. The NY sequence NEPANYŌ-TL apparently undergoes assimilation of Y to N and then degemination of the resulting NN. This is mainly used in adverbial constructions with the sense 'mutually, reciprocally.' See NEPAN-, -YŌ.
