If you're speaking to a woman and say the same thing, would it be "Tu es seule"?
Or maybe "Vous êtes seule" - it's more polite, especially if you don't know them that well :)
Not if you are using it for formality (as opposed to using it for the plural)
How do you distinguish between saying "you are alone" and "you are lonely"?
WordReference indicates that "alone" is often distinguished by the phrase "tout seul", whereas "seul" by itself seems to indicate "lonely". But it doesn't appear to be cut and dry. Perhaps "solitaire" is a better word, lacking context, to specifically indicate "lonely"?
Can I use "vous êtes seuls." when I am talking to a group of men or mixed-gender people, or "vous êtes seules." when I am talking to a group of women if they are the only group left in that area?
For "vouse êtes seul" do you pronounce "êtes" with an 's' as in with a liason? Or stop at "êt" and then continue with "seul"? (Sounds kinda unnatural) :/
How would you add a liason there? Im trying to pronounce it with a liason and i cant hear a differnece
