How are you Anupan?
I've been struggling with indirect wh-interrogatives of subject function.
How would you explain these examples?
1. He doesn't remember [who the woman who kissed him was.]
2. She has no idea [who that man is.]
How are these two different from:
3. They don't know who rang the bell.
4. I forgot who gave me this.
I've found out that subject questions (direct interrogatives) don't use any auxiliaries like 3 and 4, but I can't seem to know the difference between these and 1 and 2. Are 1 and 2 object questions?
Thanks so much in advance. more »
