Japanese sentences tend to be in noun - subject - verb order. This is different from English as English is usually noun - verb - subject order. For instance: Kawamura (noun) ate (verb) fish (subject). カワムラさん(noun)は魚(subject)を食べました(verb)。 Kawamura-san (noun) wa sakana (subject) o tabemashita (verb). Of course, even in simple sentences, particles are an important topic, but that is quite a large subject. Try to read a lot and pay careful attention to sentence structure and it will become easier to correctly form sentences yourself.
