For some mysterious reasons I find myself really interested in the Croatian culture and the beaches, and all of a sudden I am attracted to the Croatian language. I am sort of tired of learning French and I want to know what it's like to learn a Slavic language whilst I am taking a break, but since there aren't much resources on the internet and it's my first Slavic language, I find it difficult to start and I am currently being a headless chicken endlessly wandering around an empty space. I know how to pronounce words because I have a Croatian mate at school who taught me how to pronounce the words, but he said he didn't know how to teach other people his language so for now I would just leave him alone until I am proficient enough to practice with him. I've also learnt some greetings like Bok, Hvala, Doviđenja (see I even have the Croatian keyboard installed) and Nema na čemu without properly learning the grammar.
Here is my question: Should I start with the grammar, vocabulary or other things? If I start with the grammar, what methods should I use to learn the cases and conjugations? If I start with the vocabulary, what sort of words should I start with? And also, how can I easily get used to the new sentence structure?
