/estɾuɡˈtuɾa/ · B1 · noun · f
structure
🏗️ Latin structura, from struere = to build; same root as English structure
Spanish adds an e- before st-, like escuela and estado, and ends the word in feminine -a: e + structur + a. So the noun is la estructura. The same root gives construir, to build, and destruir, to destroy.
