tensión
/tenˈsjon/ · B1 · noun · f
tension
⚡ Same as English tension; both come from Latin tendere, to stretch
Latin tensio means a stretching, and it gives Spanish tensión and English tension. It has the same senses: a tense mood, physical strain, and electrical voltage (alta tensión = high voltage). The word is feminine because nouns ending in -ión are: la tensión.
