I would usually say Αυτό είναι ο καναπές μου (otherwise it sounds like I'm saying "HE is my sofa."). Have I misunderstood, and "Αυτός" can mean "this," too?
Ο καναπές is masculine (as a grammatical gender), so all words refering to it have to be in masculine form, too. In Greek, saying Αυτό είναι ο καναπές μου is like saying "that thing is my sofa", not "this is my sofa" ;)
Maybe you could add settee as a synonym for sofa?
Does καναπές share an etymology with "canopy"?
Apparently so, well spotted SauerTrout :)
In modern Greek mosquito = κουνούπι
Please let me have my settee. In day to day life I don't think I ever call it a sofa so I have to remember that duolingo will mark my settee incorrect. Could it also be a couch?
Yes, please add settee, it's the same as sofa
