Words are accented on the final syllable, but some of the endings don't count for this, so they don't change the accentuation of the words.
All prepositions take the nominative case.
The structure of a sentence follows a pattern similar to that of English, with some exceptions. First comes the subject, followed by any modifiers in order of importance. Next comes the verb, followed by any qualifiers. Next comes the object of the verb, followed by its modifiers. The direct object comes before the indirect object, unless the latter is a single pronoun.
