So, last week, through social services me and my mum got professional cleaners to clean our apartment and throw a lot of stuff out. The reason this is language-related and random is that they spoke a language neither of us recognised, and eventually my mum couldn't resist the temptation to ask. I'd have never figured it out, which is probably kind of embarrassing.
In terms of phonology it sounded very close to Turkish but was clearly not a Turkic language; it had several words that sounded extremely Slavic, too. In fact, at first (when they spoke just a couple of words together, kinda quietly) both me and my mum though it was Russian... but that was because Russian would be a common language to hear, and because the one who could speak Finnish had an accent that sounded similar to a Russian accent (the others only spoke to each other in their own language, and to us in English). The language had tons of [ʃ] and [æ]. A couple of times, I heard them say something like [kʲærdɑ], which sounded similar to the Persian verb meaning "to do", and some other stuff that sounded Indo-European... and one of them also said something like [librɑ] to another one several times, clearly referring to books.
I was confused, I had no idea what language could have that as the word for book but sound so close to Turkish in its phonology (I didn't hear a single sound that doesn't exist in Turkish AFAICT), and overall seem Indo-European. The languages I narrowed it down to in my mind were Romani or Kurdish, or that maybe they were code-switching between different languages... but I didn't think it was actually either Romani or Kurdish, because of different reasons; I figured it probably wasn't Romani because it didn't sound like it had aspirated consonants and because one of them got excited when he saw that I have a Koran (and we briefly discussed religion (in English) lol), and I figured it probably wasn't Kurdish because it had so many words that sounded Slavic and because of the Romance-like word for book.
Well, turned out it was Albanian. What this confirmed is that Albanian sounds nice, cool and is probably pretty weird (in a good way). If I wasn't feeling unable to focus on anything language-related at the moment, I'd want to learn at least a little bit of it.
