Romanian is a neo-Latin language, representing the Daco-Romanian branch of the Romanian dialects. It is derived from Vulgar Latin and it has preserved many similar grammatical structures from Latin. Over time, Romanian came in contact with many foreign influences such as Slavic, Hungarian Turkish and others.
A little taster of the grammar
Romanian has 3 grammatical genders and many endings for nouns. Some verbs in the present tense have verbal suffixes as well as the person endings to mark the various person-speakers. The adjectives have to agree in gender and number with the nouns accompanied. Many adjectives are irregular. Prepositions identify the correct case to be used after them. There are some phonetical changes that occur in words when they are being declined or conjugated.
When learning Romanian
It is advisable to keep a vocabulary book handy when learning so you can add your new words there and organise them on topics or releveance. It is also good to learn the plural of nouns for the new words as they tend to be irregular and hard to guess at times. Listening to as much Romanian as you can on internet or by watching films, and of course, when in Romania will help you with getting the accent, the right intonation and improving your pronuciation. You do not always have to unserstand what you hear, especially in the beginning, but exposure to the language is essential in learning and training your hearing.
