From what I remember from school, both Slovak and Serbo-Croatian (maybe all Slavic languages?) have this thing where "R" is behaving kinda like a vowel but it's not a vowel. Can't remember what it is called though.

Syllabic "r" [slogotvorno "r"]

American English has it too, for example in pronounciation of "work".

We have lovely words like Krk (name of an island), and Grb (cost of arms).

But even in English, my ignorant self feels the I in "Kirk" is pointless and unnecessary :-)
