Etymology: "Bipartition" is simply "bi-" attached to "partition," so it means a division into two parts. The prefix "bi-" comes from Latin "bi-," meaning "two" or "twice," and it appears in many English words such as "bicycle" and "bilateral." The base word "partition" traces back to Latin "partitio," from "partiri," meaning "to divide" or "to share out," itself from "pars," meaning "part." English gained "partition" through Old French, so the two halves of this word both reach English from Latin, with the prefix combining a number with a root meaning part. Because "bipartition" is a transparent compound, its meaning is clear from its parts, and it is mostly found in technical and formal contexts, such as mathematics, biology, and politics, where a whole is deliberately split into exactly two pieces.
