стъкло (stăklo) in Bulgarian
Стекло in Russian
Straight-up borrowing from Slavic languages, usually meaning "glass".
I thought bottle in Russian is sth. like Bunka, right?
Like "botella" in Spanish
yes, very similar, but not the same
Well hey, when are we supposed to distinguish between bottle and glass, when sticlă is the only word?
sticla ( as an object ) =bottle. Sticla (as a material ) = glass
And then what is glass (drinking vessel)?
