Georgian numerals

This article contains Georgian text. Without proper rendering support, you may see question marks, boxes, or other symbols instead of Georgian letters.

The Georgian numerals are the system of number names used in Georgian, a language spoken in the country of Georgia. The Georgian numerals from 30 to 99 are constructed using a base-20 system,^[1]^[2]^[3] similar to the scheme used in Basque, French for numbers 80 through 99,^[4] or the notion of the score in English.

The symbols for numbers in modern Georgian texts are the same Arabic numerals used in English, except that the comma is used as the decimal separator, and digits in large numbers are divided into groups of three using spaces^[5] or periods (full stops). An older method for writing numerals exists in which most of the letters of the Georgian alphabet (including some obsolete letters) are each assigned a numeric value.^[6]

^ Hewitt (1995), p. 524. "The system from '11' to '19' is analysable as '10-UNIT-more'. From '20' to '99' the system is based on units of 20 (i.e. it is vigesimal, so that, for example, '55' is literally '2-times-20-and-(10-5-more)'."
^ Makharoblidze (2009), p. 27. "[The] Georgian system of numbers is based on the counting system of 20. The numbers more than 20 and less than 100 are compound and the first number is [20 multiplied by the preceding numeral ("1" is not shown)] and then [the] remaining number is added."

Base '20' can also be used more sporadically in a system that is basically decimal ... French shows such vigesimality only in the range '80'–'99', with '80' expressed as quatre-vingts 'four-twenties', '91' as quatre-vingt-onze 'four-twenty-eleven', etc.
