Modern Hebrew is a language that emerged in the late 19th century, based on different dialects of ancient Hebrew and somewhat influenced by many languages (English, Jewish languages, Slavic languages, Arabic, Aramaic, German and others). Hebrew and Arabic are the official languages of Israel.
Some academics consider the Hebrew language one of the hardest to learn, but in fact, millions of new immigrants to Israel, of all ages and from all over the world, have managed to learn to speak Hebrew fluently, so there isn't any reason you can't do the same if you set your mind to it.
