Usage and Linguistic Rules In the French numbering system, the integers from 11 ( onze ) to 16 ( seize ) follow a unique lexical pattern derived from Latin. Conversely, the numbers 17, 18, and 19 are constructed using a compound structure where the base ten ( dix ) is hyphenated with the units seven, eight, and nine respectively. A significant phonological rule to observe is the liaison ; for instance, in dix-huit , the "x" is pronounced as a "z" sound because it precedes a vowel sound. Furthermore, in the number vingt , the final "gt" remains silent unless it is followed by a word beginning with a vowel, in which case the "t" may be articulated. These numbers serve as the fundamental building blocks for expressing time, currency, and quantities in all formal and informal French discourse.
