/jêtra/
PodrijetloInherited from Proto-Slavic *ętro, from Proto-Indo-European *h₁entrom. The noun was originally of neuter gender in Proto-Slavic and Proto-Indo-European, but since it was chiefly used in plural (with the ending -a for neuters) it became remodeled as a feminine singular noun. First attested in the 16th century.
