-ome

anglicized form of -oma (partly through influence of G. -om, F. -ome), occurring chiefly in Bot. in terms such as caulome, hadrome, phyllome, rhizome, and usu. signifying a structure or group of cells forming a normal part of the anatomy, in contrast with the abnormality implied by -oma (cf. mycetome, an organ in insects, mycetoma, a fungal skin disease). It also occurs in a few obs. forms of words now written -oma, e.g. fibrome, tuberculome.
