Czech Language/Cardinal Numbers

In Czech, the word for number is číslovka. The plural of číslovka is číslovky. A cardinal number (základní číslovka) is a counting number: one book (jedna kniha), two books (dvě knihy). Notice that numbers are adjectives and, as such, must agree in gender with the noun it modifies. However, only the cardinal numbers one and two have a changeable gender. The number 'one' is jeden, jedna, and jedno (masculine, feminine, and neuter). The number 'two' is dva and dvě (masculine and feminine/neuter). Thus, one table (jeden stůl), one pencil (jedna tužka), one window (jedno okno), two dictionaries (dva slovníky), two chairs (dvě židle), and two airplanes (dvě letadla).

Note on Very Large Numbers
Please note that the Czech Republic uses the long scale for numbers like most European states. The United States uses the short scale.
