On sentence-initial interrogative particles, I said:
This is unusual among Indo-European languages in Europe, Latvian being another exception.
forgetting the example I knew fine from my native Lothian Region (as it was at the time), “eh”. I don’t recall seeing this written down, though, and my Concise Scots Dictionary has nothing relevant under “eh”, “ae” or “ay”. An example?
Eh there’s a sentence-initial interrogative particle you know already?
Er, and Polish czy.
