The Russian language does not have articles (like the or a in English, or la or le in French). Since you can't tell the gender of a noun by looking at its article, you have to look at the noun's ending. Russian masculine nouns end in consonants, as in chelovek (person); in -j (i kratkoe), as in muzej (museum); or -' (soft sign), as in uchitel' (teacher).
