I understand that kik is plural, but I don't think "who are" is possible in English in this context. (Although I am a native speaker, I admit I could be wrong.)
Yes, it is an English irregularity, but in English, we would say 'Who is' in this instance, but not always (eg. Who are they?)
I disagree (native American English speaker, living in New Zealand for more than a decade). We could easily say "who are hurrying into the new building".
Could someone explain why it isn't besietnek but sietnek be please? Thank I you in advance!
