- Why is 70 soixante-dix in French?
- France French counts 70 to 99 in twenties rather than tens. 70 is soixante-dix (60 + 10), 80 is quatre-vingts (4 x 20), and 90 is quatre-vingt-dix (4 x 20 + 10). Belgium and most of Switzerland use septante and nonante instead, and parts of Switzerland also use huitante.
- When do you say et un instead of a hyphen?
- 21, 31, 41, 51, 61 and 71 use et with no hyphens: vingt et un, soixante et onze. 81 and 91 do not: quatre-vingt-un and quatre-vingt-onze. The 1990 spelling reform hyphenates all of them, so vingt-et-un is also correct.
- Why does six sound different in six ans and six personnes?
- The final consonant of six, dix, huit, neuf, vingt and cent depends on what follows. Alone, six is seess (/sis/). Before a consonant it is see (/si/), as in six personnes. Before a vowel the z moves onto the next word: six ans is see-zahn (/si.zɑ̃/).
- Why is neuf ans pronounced with a v?
- neuf is the only French number whose final -f becomes a v sound, and only before ans and heures. neuf ans is nuh-vahn (/nœ.vɑ̃/) and neuf heures is nuh-vuhr (/nœ.vœʁ/), but neuf euros keeps the f: nuh-fuh-roh (/nœ.fø.ʁo/).
- When does quatre-vingts take an -s?
- Only when nothing follows it. quatre-vingts and cent quatre-vingts keep the -s, but quatre-vingt-deux, quatre-vingt-dix and quatre-vingt mille drop it. cent works the same way: deux cents, but deux cent un. mille never takes an -s.
