Someone has just found out that someone else is Belgian.
1. “Huh. I thought he was French.”
Or they say,
2. “Huh. I thought he’s French.”
I’d say the former. I believe that’s the subjunctive, right?
I’ve sometimes heard sentences like the latter, though. It sounds slightly wrong to me but I’m unable to articulate quite why it is wrong.
What do you reckon? Is 2. “widely accepted” or “criticised by scholars”?
