Germ Means a Seed, Which Is Why Ideas Have Them
A germ is a microbe. The word first meant a seed or sprout, which explains the germ of an idea.
A germ is a micro-organism that causes disease, and also the seed or earliest form of something. Latin *germen* meant a sprout or bud, and the biological sense came from the idea of a disease growing from a tiny seed — germ theory took its name from that image. The wheat *germ* is the seed embryo, the original sense used exactly. That is also why an idea can have a germ: the smallest form from which the whole thing grows.
