Alteration of -oma, removing the case ending retained from its Ancient Greek [Term?] etymon -ωμα (-ōma). Partially cognate to -some (“body”), from σῶμα (sôma, “body”), in that both share the case ending -μα (-ma), but the ω is unrelated.
-ome
Back-formation from mitome, reinforced by chromosome. Early examples include biome (1916) and genome, from German Genom (1920).[1] Some association with genetics due to occurrence in chromosome and genome.
