Etymology: "Cultriform" is a plain technical coinage built from two parts. The first is Latin "culter," meaning "knife" (genitive "cultri"), which gave English words like "culter" and "coulter," the iron blade on a plough that cuts the soil ahead of the share. The second part is the combining element "-form," from Latin "forma," meaning "shape," which scientists attach to roots to describe things having a particular shape, as in "cruciform" (cross-shaped) or "filiform" (thread-shaped). Put together, "cultriform" describes something shaped like a knife blade. Its use is mainly in botany and morphology, where a leaf, petal, or other plant structure is narrow, straight-edged, and tapering to a point like a blade. Writers use it in precise descriptions rather than everyday speech, which is typical of words built this way in scientific Latin.
