What it means
بسیار (besyâr) is a formal adverb meaning “very,” “much,” or “a great deal.” It is a pure Persian word with roots in Middle Persian bisyâr, and it appears in classical texts going back over a thousand years. In modern Persian it functions as the formal counterpart to the everyday خیلی (kheyli): both mean “very” or “a lot,” but بسیار belongs to literary, official, and elevated registers, while خیلی is the word of the street and everyday conversation. You will find بسیار throughout poetry, formal speeches, news writing, and traditional expressions. As an adverb it typically precedes an adjective or verb.
How to use it
- این کتاب بسیار ارزشمند است. (In ketâb besyâr arzeshmand ast.) “This book is very valuable.”
- بسیار ممنونم از لطف شما. (Besyâr mamnunam az lotf-e shomâ.) “I am very grateful for your kindness.”
- این موضوع بسیار پیچیده است. (In mowzu besyâr pichide ast.) “This subject is very complex.”
- در آن روزها بسیار کار میکردیم. (Dar ân ruzhâ besyâr kâr mikardim.) “In those days we worked a great deal.”
Cultural note
بسیار carries a sense of literary dignity that خیلی does not. When Iranian poets, classical writers, or orators use بسیار, it evokes the long tradition of Persian literature from Hafez to Saadi. In contemporary speech, choosing بسیار over خیلی signals education, formal intent, or deliberate stylistic elevation. It is also frequently heard in the formal speech of older generations and in religious or ceremonial contexts. Learning بسیار is a small key that unlocks access to Persian classical poetry and formal prose.
