What it means
لیمو ترش (limu torsh) means sour lime, the small green or yellow citrus used throughout Persian cooking for its sharp acidic juice. The compound joins لیمو (limu), an ancient word for citrus that traveled through Sanskrit nimbū, which was itself borrowed from an Austroasiatic language before the chain reached Persian, with ترش (torsh), the native Persian adjective for sour. Persian borrowed or co-developed limu very early, and the word later passed into Arabic as laymun and from there into European languages as lemon and lime. A natural contrast is لیمو شیرین (limu shirin), the sweet lime, which is much milder and eaten like fruit rather than used as a souring agent.
How to use it
- یه لیمو ترش رو آب بگیر. (ye limu torsh ro ab begir.) “Squeeze the juice from a lime.”
- غذا لیمو ترش میخواد. (ghaza limu torsh mikhad.) “The food needs lime.”
- دو تا لیمو ترش بده بهم. (do ta limu torsh bede beham.) “Give me two limes.”
- با لیمو ترش طعمش بهتر میشه. (ba limu torsh taemash behtar mishe.) “The flavor gets better with lime.”
Cultural note
Lime juice is an essential souring agent in Persian cooking, used to balance the richness of stews such as ghormeh sabzi and khoresh-e fesanjan, and squeezed over grilled meats. Dried limes, called limoo omani or limu amani, are a distinct ingredient: whole limes dried until hard and dark, then added to soups and stews to give a more complex, slightly fermented tartness that fresh lime cannot replicate.
