There is a sentence:
Третий сидящий за столом - доминиканец...
The question is: do I need a comma after "третий"? There could be 2 variants of interpretation of the sentence's structure:
- "Третий" is a subject and "сидящий за столом" is participial clause, there is a need for comma
- "Сидящий за столом" is the subject, "третий" is an attributive adjective, no need for a comma
Which case here is then correct?
