 While -ҳо can be used with any noun, the suffix -он is primarily used with animate nouns and has the variants -ён (-yon) which is used with words ending in -ӣ, ӯ or -о, -вон (-von) for words ending in у, and -гон (-gon) which is used with words ending in -а.For example, the singular for 'horse' is асп ("asp"), and the plural, 'horses' can be either аспҳо ("aspho") or аспон ("aspon").Typically, the -он ("-on") ending is reserved for animate objects, although this is not always true.
