Latin has three genders: Masculine, Feminine and Neuter. For nouns of the 1st and 2nd declensions you can usually tell the gender of a noun by its nominative singular ending.
Nouns of the 3rd declension may occur in all three genders. Nouns of the 4th declension are masculine, with some exceptions. Nouns of the 5th declension are feminine, with exceptions.
Latin word-order is not fixed. The subject and object are distinguished by their cases. Verbs generally are placed at the end of a sentence. Adjectives of quantity usually precede their noun (e.g. magnum opus) while adjectives of quality usually follow it (e.g. terra firma). And adjectives of nationality follows (e.g Lingua latina).
Latin has six cases.
- Nominative (subject)
- Accusative (direct object)
- Genitive (possessions)
- Dative (after to or for and some verbs e.g. credere)
- Ablative (after other prepositions, unless movement is implied in which case accusative is used)
- Vocative (to call someone's name, not used very often)
