## List of numbers appearing in linguistics

- There are
**26**letters in the Latin alphabet, and 24 in the Greek alphabet. - There are
**676**two-letter combinations formed from the ISO basic Latin alphabet.- It is also the second largest [[1]] square number; this has been proved by David Moews.
- 676 is an even perfect square number (676 = 26
^{2}). - Prime factorization of 676 is 2
^{2}× 13^{2}.^{[1]}

- There are
**702**one- and two-letter combinations formed from the ISO basic Latin alphabet; they are used in chemical element symbols and vehicle registration plates of Germany. - There are (including zero) 19 possible onsets, 21 possible nuclei and (including zero) eight possible codas in the spoken Korean language, resulting in
**3,192**possible syllables. - There are (including zero) 19 possible onsets, 21 possible nuclei and (including zero) 28 possible codas in the written Korean language, resulting in
**11,172**possible syllables. - In the German language, the number
**12,000**is called “zwölftausend”. It is the largest number, whose German name contains different letters.- It was also the prize for correctly answering the first five questions in the French game show

- There are
**17,576**three-letter combinations formed from the ISO basic Latin alphabet. - There are
**456,976**four-letter combinations formed from the ISO basic Latin alphabet. **8,549,176,320**not only contains every decimal (base 10) digit (0-9), but all the digits are placed in alphabetical order:- 8 =
**e**ight, 5 =**fi**ve, 4 =**fo**ur, 9 =**n**ine, 1 =**o**ne, 7 =**se**ven, 6 =**si**x, 3 =**th**ree, 2 =**tw**o and 0 =**z**ero. - Its prime factorization is: 2
^{10}× 3^{3}× 5 × 61,843. - The following are numbers that satisfy this property in other languages:
