Is there a difference (in the meaning) between the two sentences below? Are they both correct? When can I use them?
1) I appear to be suspicious.
2) I appear suspicious.
Yes, there is a huge difference!
I appear to be suspicious means it has become apparent that you are suspicious of someone or something.
I appear suspicious means that someone observing you would suspect you of something.
I'm not sure what rule of English is at work here. I just know what I'd think if someone uttered one of those sentences.
Agree.
I appear to be suspicious You are suspicious of smth and maybe,don't trust to anyone or anything else
I appear suspicious The others think that you're suspicious
