 The numerals 1 and 2 as well as 21–29, 31–39, 41–49 correspond with the counted in the grammatical gender, while the numerals 3–20, 30, 40 and 50 are characterized by polarity of gender, i.e.if the counted noun is masculine, the numeral would be feminine and vice versa.This polarity is typical of the Semitic languages and appears also in classical Arabic for example.
