I came about the French word "eux". I'm a bit confused of the proper usage of the word. Is it "them" or "they", or do the usages not correspond? When is eux used in French?
French language is always tricky, so I'll say, both and more :)
If "Eux" is used as a subject, it's they. Ex: "Je voulais venir, mais eux ne voulaient pas" => "I wanted to come, but they didn't".
If it is used to induce a possession, it's their. Ex: "Je vais chez eux" => "I'm going to their house"
Finally, you can also find it used as an object, and then it's them. Ex : "Tu les as vus?" => "Have you seen them?"
