Romanian is a Romance language spoken mainly in Romania and Moldova, as well as in some parts of Hungary, Serbia and Montenegro, Bulgaria and Ukraine. It is useful to know the language if travelling in Romania, especially in rural areas, and even though nowadays nearly everyone knows some English, your experience in the country will be so much better and friendlier if you speak the local language.
Romanian is a fairly difficult language to learn and speak, due to its complicated grammar. It is, however, fairly similar to Italian, and, to an extent, French, so speakers of these languages are more at an advantage.
Even though Romanian pronunciation is very phonetic, a lot of foreigners find it hard to speak it, especially English speakers. The accent and sounds are very similar to Italian (with slight Slavic influences), so remember to sound every letter clearly. Also, sounds very rarely differ between words (i.e. the letter i is always pronounced the same, everytime, unlike in English).
NOTE: The pronunciation guides in brackets beside each word only act as guides, due to the fact that they will make the Romanian word have a strong English accent. To get a better pronunciation, it is generally better to look at the Pronunciation Guide above and learn the right pronunciation for each letter (this is easier than it sounds)
