Questions & Answers about Mon cousin cherche son chien.
Why is it son chien? If the cousin was a woman, would it be sa chien?
No, it would still be son chien! In English, we use "his" or "her" based on who owns the dog. In French, possessive words like son (his/her) and sa (his/her) must match the gender of the thing being owned. Because chien is a masculine word, you must use son, regardless of whether the owner is a man or a woman.
I am a woman. Should I change it to ma cousin?
No, your own gender doesn't change the word for "my". The rule from the previous question applies here too: the possessive word matches the noun it sits next to. Since you are talking about a male cousin (cousin), you use the masculine mon. If you were talking about a female cousin, the noun changes to cousine, so you would say ma cousine.
Where is the word for "for" in this sentence? Why isn't it cherche pour son chien?
Why does the verb cherche end in "-e" here?
