What does detente mean?
Détente refers to an easing of strained relations, most famously between rival states during the Cold War, when the United States and the Soviet Union pursued negotiated arms control and broader diplomatic engagement in the 1970s. As a noun borrowed directly from French, it denotes not a permanent peace but a deliberate loosening of hostility — a thaw that can deepen into cooperation or reverse back into confrontation. Beyond geopolitics, the word is used figuratively for any cooling-down of conflict, such as a truce between feuding colleagues or business partners. Its connotations are largely positive, suggesting pragmatism and mutual restraint rather than victory or friendship, which is why it suits situations where enemies merely agree to stand down. Because of its diplomatic pedigree, détente carries a somewhat formal register and remains a precise, evocative term for describing moments when long-standing adversaries choose dialogue over escalation.
nounAn easing of strained relations, especially between nations or political rivals; a period of reduced hostility and improved diplomatic engagement.
- A formal easing or relaxation of strained relations, especially between rival states.
- (By extension) any general reduction of tension between people or groups.
"The arms-control treaty marked the high point of superpower détente."
"Historians still debate whether the 1970s détente genuinely reduced the risk of nuclear war."
"After months of feuding, there were hints of a détente between the two co-founders."
Rarely pluralized; the word typically appears uncountably or in the singular even when referring to multiple periods of eased tension.
"Historians compare the various detentes of the twentieth century."
Before it described superpower diplomacy, 'détente' was the technical term for relaxing the spring of a trigger — the word itself began as a release of tension.

Etymology of detente
The word entered English from French détente in the early twentieth century, though its diplomatic sense became widespread during the 1960s and 1970s. It derives ultimately from the Latin verb detinēre, meaning 'to hold back' or 'to restrain', formed from de- plus tenēre ('to hold'). In earlier usage, French and English both applied the word to the literal loosening of a mechanical tension, such as the spring of a trigger, before it came to signify the relaxation of political strain. It shares this Latin root with English words such as detain, contain, tenant, and tenure.
How detente is actually used
Usually written in English without the French accent (détente is also acceptable). Strongly associated with Cold War diplomacy, particularly US–Soviet relations in the 1970s; extended figurative uses are common but carry a slightly formal tone.
