The word "но" is a conjunction in the Russian language that translates to "but" in English. It is used to introduce a contrast or exception in a sentence. For example, one might say, "Я люблю чай, но предпочитаю кофе," which means "I love tea, but I prefer coffee." In addition to contrasting ideas, "но" can also indicate a shift in thought or introduce an unexpected outcome. It helps to connect sentences smoothly while highlighting differences. Understanding how to use "но" effectively can enhance communication in Russian and improve overall language skills.
