- źěśe (obsolete)
From Proto-Slavic *dětę, from Proto-Indo-European *dʰeh₁- (“to suckle, suck”). Cognate with Upper Sorbian dźěćo, Polish dziecię, Czech dítě, Old Church Slavonic дѣти (děti), and Russian дитя (ditja).
This word is in a suppletive relationship with góle. In the nominative and accusative singular, źiśe and góle are both found; in these cases góle implies a young child (up to about 6 years old) and źiśe a somewhat older one. The genitive, dative, instrumental, and locative singular as well the entire dual are formed from góle, while the plural is formed from źiśe; in these cases there is no semantic distinction between the two roots.
