The Latin word tendere, meaning to stretch or to spread, and its form tentus give us the roots tend, tent, and tens. Words from the Latin tendere have something to do with stretching or spreading. A tent is a temporary shelter made from stretched out fabric. To distend is to stretch outward and swell in all directions. To extend is to stretch out.
