As a Romance language, Romanian has a lot in common with other Romance languages. Romanian vocabulary is 77 percent similar to Italian, and 71 percent similar to Spanish. If you speak either of those languages, you likely already know quite a few Romanian words and phrases.  For example, the Romanian word for "city" is cetate. Compare this word to the English word "city," the French word "cité," the Italian word "città," the Portuguese word "cidade," and the Spanish word "cuidad." There are thousands of cognates among all Romance languages and English if you look at combinatorial forms – words that end with a suffix, such as -tion, -ent, or -able. For example, any English word that ends in -tion has a cognate in a Romanian word that ends in -tune. By learning these forms, you can add thousands of words to your vocabulary. The rhythm and repetition of music make it an easy way to learn simple phrases in a language. You can find Romanian music on most streaming services, as well as on YouTube videos. You can also find a list of Romanian radio stations that stream online for free at https://www.101languages.net/romanian/romanian-radio/. Film and television are a great way to listen to native speakers conversing in Romanian. Search online for free films and television shows that you can watch. You may also be able to find Romanian films in the foreign language section of your favorite video-streaming service.  You likely won't pick up a lot of Romanian just by passively watching a movie or a television show. It can help to start with English-language captions, so you understand what's going on. Through time and repetition, you'll start understanding more Romanian words. At that point, you can turn the captions off. You can also turn on closed-captioning in Romanian to learn more about what the spoken words look like when written out. The Live Lingua Project makes US government language learning materials available for free online. For Romanian, the project has 4 different Peace Corps packages, including a 126-page eBook on Romanian grammar. The materials are relatively dated but can help you get a better understanding for the language and how it's structured. There are also exercises and quizzes that can help you practice what you've learned. Reading children's books is a great way to learn basic grammar and vocabulary in any language. While there aren't many Romanian children's books available for free online, there are some available for purchase at major retailers, such as Amazon.  Project Gutenberg has a few Romanian ebooks available to download for free at http://www.gutenberg.org/browse/languages/ro. Once you have a little more reading skill, you might try to read Romanian newspapers. There's a list of Romanian newspapers available online at https://www.101languages.net/romanian/newspapers/. There are many websites and smartphone apps that offer flash cards and other word games that can help you develop and expand your Romanian vocabulary. Crossword puzzles may also help improve your spelling. Many of these are available for free, while others require you to purchase a subscription. The website Surface Languages has Romanian crosswords, word searches, and other word games available for free.
