germane

This word began life in Latin as germanus, a plain family term for siblings who shared the same parents. English first borrowed it in the 1300s for blood kin, which is why old phrases like cousin german once meant a first cousin — not a German cousin, just a very close one. Then Shakespeare nudged it in a new direction in Hamlet, where a line about something being “more Germaine to the matter” helped turn a kinship word into a word for relevance. That’s the fun part: the same family-image that says two people belong together now tells us an argument belongs together, too. It sits beside cousins like humane and urbane — words that look noble and polished, but started out as ordinary Latin descriptors before English dressed them up. Tomorrow, if something fits perfectly, you can think: same family, same room, same idea.
