What it means
خیر (kheyr) carries two distinct but connected meanings in Persian. As a response particle it is the formal and polite way to say no, used in situations where the casual نه (na) would feel too blunt, for example when speaking with elders, superiors, or in professional settings. As a noun, kheyr means goodness, well-being, blessing, or charitable giving, which is its older Arabic-origin core. The two meanings meet in social graces: when someone does you a favour and you decline a reward, saying خیر ممنون (kheyr mamnun, no thank you, in a formal register) signals both refusal and appreciation. The noun sense surfaces in phrases like کار خیر (kâr-e kheyr, a good deed or charitable act) and خیریه (kheiriyye, a charity or charitable organization).
How to use it
- خیر، ممنونم (kheyr, mamnunam) “No, thank you. (polite)”
- خیر خبری نیست (kheyr khabari nist) “No, nothing to report. (formal)”
- این کار خیره (in kâr-e kheyre) “This is a good deed / act of charity.”
- به خیریه کمک کردن (be kheiriyye komak kardan) “To donate to charity.”
Cultural note
The split between خیر (formal no) and نه (casual no) is a live diglossic pair in Persian that learners notice quickly. In a job interview, in front of a teacher, or when speaking with someone older, خیر signals awareness of social register. Saying نه in those contexts is not wrong, but خیر shows politeness. The noun sense of kheyr is woven into Iranian ethical and religious culture: کار خیر and خیریه appear in mosque fundraising, hospital naming, and everyday conversation about giving. The greeting phrase اِن شاءالله خیر باشه (hopefully all is well) also draws on this root.
