What it means
روغن (roghan) means oil or fat, covering everything from vegetable cooking oil to animal grease to ointment. The word comes from Middle Persian rōγn, which itself descends from Proto-Iranian rawgnah, making it one of the most deeply rooted words in the Iranian language family. It is cognate with Pashto roğan, Kurdish ron, and the Rogan Josh dish name. In the kitchen, روغن (roghan) contrasts with کره (kare, butter): کره is solid dairy fat, while روغن is any pourable or rendered fat. You will often hear compound forms such as روغن زیتون (roghan-e zeytun, olive oil) or روغن نباتی (roghan-e nabati, vegetable oil).
How to use it
- یه کم روغن تو تابه بریز. (Ye kam roghan to tabe beriz.) “Pour a little oil into the pan.”
- روغن زیتون برای سالاد خوبه. (Roghan-e zeytun baraye salad khube.) “Olive oil is good for salad.”
- این غذا روغن زیادی داره. (In ghaza roghan-e ziadi dare.) “This food has too much oil.”
- روغن تموم شد، باید بخریم. (Roghan tamum shod, bayad bekhrim.) “The oil ran out, we need to buy some.”
Cultural note
Persian cooking relies on a generous hand with روغن (roghan), and the glistening surface of a well-made khoresh or polo is considered a mark of quality, not excess. Traditionally, روغن حیوانی (roghan-e heyvâni, animal fat) and روغن دنبه (fat from sheep tail) were the household standards before vegetable oils became widely available in the twentieth century. The word also entered Turkish and several South Asian languages, carrying its meaning of oil or grease wherever Persian culinary and courtly culture traveled.
