Questions & Answers about Leurs projets internationaux sont géniaux !

Why do internationaux and géniaux end in -aux instead of just adding an -s?
These are the masculine plural forms of international and génial. In French, when a masculine singular adjective or noun ends in -al, it almost always drops the -al and changes to -aux in the plural.
Would feminine words also use this -aux ending?
No, the -aux rule is only for masculine words! If the noun were feminine, like idées (ideas), you would just add an -s to the feminine singular form. The sentence would become: Leurs idées internationales sont géniales !
Why does Leurs have an -s at the end? Doesn't leur already mean 'their'?
Yes, but possessive words in French must match the noun they are describing. Because projets is plural (there is more than one project), you must use the plural form leurs. You would use leur without the -s only if they had one single project (leur projet).
How do you pronounce the -x at the end of internationaux and géniaux?
You don't! The -x at the end of these plural words is completely silent, just like a regular plural -s. Both words end with a sound similar to the 'o' in the English word 'so'.
