indicate whom among us is ignorant of Polish.
You are getting worse by the minute, professor. "Whom"
? Are you serious or just testing me? No, professor, it's "who among us is...", not "whom".
Do you know why? It's so because the answer is he
, not him.
For example: He
among us is the tallest.
Getting too professorial with English is a very bad habit that leads to bad places.
