Resumen de Zur Wortgeschichte von Gummi
One of the few Egyptian words occuring in most modern languages is ḳmj.t, Coptic ком(м)є or ком(м)ι, Greek κóμ(μ)ι. It is normally indeclinable, but in the papyri it has passed mostly to the consonantic declination (gen. κóμμεως). Latin evidence proves that the vulgar variant gumma (instead of gummi or cummi) is the etymon of Romance forms like Fr. gomme, which passed to other languages (English gum, German Gummi).
