What it means
خیانت (khianat) is betrayal, treachery, the breaking of trust by someone whose trust you had. The word is heavy. Iranians do not deploy it lightly; calling someone’s act khianat is to place it on the harshest moral shelf available in everyday speech. The opposite is وفاداری (vafadari, loyalty), and the two define a single ethical axis that organizes how Iranians talk about marriages, friendships, business partnerships, and political allegiance.
The word covers a range. Sexual infidelity in marriage is khianat. Selling a friend’s secret is khianat. A general turning his army against his country is khianat. The seriousness scales, but the moral category does not soften: any breach of trust by someone trusted earns the name.
How to use it
Khianat is a noun. The verb form is خیانت کردن (khianat kardan, to betray). The agent is خائن (kha’en, a traitor). The phrase خیانت در امانت (khianat dar amanat) is a legal-grade phrase meaning breach of fiduciary trust, used in courts and contracts.
khianat-e oun hamsarash ra shekast.
His betrayal broke his wife.
خیانت او همسرش را شکست.
in kar khianat be eshq ast.
This act is a betrayal of love.
این کار خیانت به عشق است.
khianat dar amanat jorm-e sangini ast.
Breach of fiduciary trust is a serious crime.
خیانت در امانت جرم سنگینی است.
Khianat in Iranian marriage discourse
When Iranian friends and families discuss a marriage in trouble, khianat is the diagnostic word. It does not require a confession or a court; community judgment uses it freely once the evidence accumulates. The asymmetry to notice is that khianat against a wife and khianat against a husband are not always weighted equally in traditional speech, with a woman’s khianat historically treated as more catastrophic. Modern urban discourse increasingly rejects this asymmetry, but the older weight is still in the language.
Where it comes from
Khianat is Arabic, from the root خ-و-ن (kh-w-n, to be unfaithful, to betray). The same root gives the agent noun خائن (kha’en, traitor) and the verb form خوّن (khawwana, to charge with treachery). Persian borrowed the word through Quranic and legal Arabic, where khianat is a named moral and juridical category. The Quranic context, especially the prohibition on khianat in trusts and treaties, gave the word its weight in Persian ethical writing, and that weight has carried into everyday speech.
In our voice
If you only learn one of the vafadari and khianat pair, learn this one. It is the word you will encounter in films, novels, and family arguments. Knowing its weight will keep you from translating it casually as cheating and missing the whole moral register the word carries.
