What does tension mean?
Tension names several related kinds of strain. Most often, it means anxiety, unease, or nervous suspense; in relationships, it denotes hostility or conflict; and in mechanics, it refers to the pulling force or tautness of a stretched object. These usages share an idea of pressure: emotional pressure, social friction, or physical force working against resistance. The word is also used figuratively for a sharp difference between principles, descriptions, or expectations. As a verb, tension is relatively uncommon and chiefly technical or formal; it means to make something taut or to increase the strain on it. Because one word spans both the felt sensation of being wound up and the literal force that stretches a cable, tension is useful in discussions of psychology, politics, storytelling, and engineering. Its direct Latin origin, from tendere, “to stretch,” also connects it to tendency, tensile, tendon, and intention. The word thus remains a compact label for pressure in many directions while distinguishing the specific nature of that pressure.
A state of anxiety, emotional strain, or uneasy tension; strained or hostile relations between people or groups; or physical tautness or pulling force.
"The negotiations were conducted under considerable tension."
The abstract emotional and interpersonal senses are dominant in ordinary modern usage; the physical sense remains common in technical contexts.
To make something taut or to increase the strain on it.
"The crew tensioned the cable before lifting the load."
This use is chiefly technical or formal and is much less common than the noun.
The plural often refers to multiple strained relationships, conflicts, or sources of anxiety.
"The agreement helped reduce the tensions between the two communities."
Tension grew from the Latin tendere, “to stretch”—the same root behind tend, intent, and the taut feeling of something under pressure.

Where does tension come from?
Tension comes from Latin tēnsiō, meaning “stretching” or “tension,” formed from tendere, “to stretch.” The English word developed from physical meanings referring to strain and tautness before being extended to emotional strain and strained relations. Its wider Latin family includes tendency, tensile, tendon, and intention, all associated with the same root.
