Etymology: "Biparous" is built from two parts: the Latin prefix "bi-", meaning "two", and "-parous", from Latin "parere", "to bring forth" or "to bear." The "-parous" ending is the same element found in "viviparous" (bearing live young) and "oviparous" (laying eggs), so "biparous" slots into a family of biological terms describing how animals reproduce. Its meaning follows directly from those parts: "bearing two young" at a single birth or in a single litter. Naturalists used this kind of formation to sort animals by reproductive pattern, so the word belongs to the technical vocabulary of zoology rather than everyday speech.
