بو

What it means

بو (bu) is a pure Persian noun meaning smell, scent, or odour. The word is neutral by itself: it names the sensory category without evaluating it. Context and modifiers carry the positive or negative charge. بوی خوب (bu-ye khub) is a good smell; بوی بد (bu-ye bad) is a bad smell; بوی غذا (bu-ye ghazâ) is the smell of food; بوی عطر (bu-ye atr) is the scent of perfume. The compound بو دادن (bu dâdan) means to give off or emit a smell (intransitive), while بو کردن (bu kardan) means to smell something deliberately, to sniff it. The related verb بوییدن (buidodan) carries the same meaning as بو کردن but is slightly more formal or literary. In colloquial speech بو کردن is far more common. بو also appears in a figurative sense: بوش رو می‌دم (bush ro midam) means “I’ll tip you off” or “I’ll give you a hint,” literally “I’ll give you its smell.”

How to use it

• بوش خوبه (bush khube) “It smells good.”
• بو میده این ماهی (bu mide in mâhi) “This fish smells.”
• بذار بو کنم (bezâr bu konam) “Let me smell it / Let me have a sniff.”
• بوی قهوه رو دوست دارم (bu-ye ghahve ro dust dâram) “I love the smell of coffee.”

Cultural note

In Persian culture, smell carries strong associative and emotional weight. The بوی نان تازه (the smell of fresh bread) is a cultural touchstone, as neighborhood bakeries (نانوایی, nânvâyi) that produce fresh sangak or barbari every morning are a central feature of Iranian urban life. The smell of rose water and saffron is tied to celebrations and religious rituals, and بوی بهار (bu-ye bahâr, the smell of spring) is almost a poetic cliche in Persian. Beyond food and nature, بو has a folk-medicine dimension: many Iranians hold that certain smells indicate illness, and expressions like بوی تنش تغییر کرده (the smell of their body has changed) are used as informal indicators of health changes.
