The Etymology of Durable
The hardness of wood gave humanity its word for truth, and durable sits in the same ancient family.βββββββββββββββββββββββββββββββββββββββββββββββββββββββββββββββ Proto-Indo-European *deru- meant 'tree' or 'wood,' and the concept of woody firmness branched in two directions. Through Germanic, it produced tree (the object), true (what is firm and reliable), trust (confidence in firmness), and even truce (a firm agreement). Through Latin, it became dΕ«rus (hard), which generated dΕ«rΔre (to last, to harden), dΕ«rΔbilis (able to endure), and eventually English durable, endure, duration, and duress. The idea connecting all these words is that what resists pressure β like seasoned hardwood β is what persists and can be relied upon. English borrowed durable from Old French in the fourteenth century for physical resilience: durable goods, durable materials, durable construction. The word has remained remarkably stable in meaning, resisting the semantic drift that transforms so many borrowings. Economics formalised it further with 'durable goods' β products expected to last three years or more. Latin dΕ«rus also left its mark through less obvious channels: the word during comes from the same root, as does the musical term durata.
