ऊधस्

Etymology
Ultimately from, whence also the r-stem which see for cognates.

Noun

 * 1) the udder of any female, breast, bosom
 * 2) the night

Usage notes
In classical Sanskrit the stem appears only in the feminine of an adjective compound, while the original heteroclitic r/n paradigm has been preserved in Vedic; compare nominative and genitive singular  ~.
