I'm suspicious of him./He's suspicious to me.

[Marika33]

Do these two mean (almost) the same thing?

1. I'm suspicious of him.
2. He's suspicious to me.

 

[Tarheel]

No.

 

[jutfrank]

Yes. (Sorry to directly contradict you, @Tarheel.)

 

[Tarheel]

"I'm suspicious" says something about the speaker's attitude. "He's suspicious" says something about "his" attitude (whoever he is). As for "He's suspicious to me", that's not a phrase I'm familiar with, but since it starts "He's suspicious" it would seem to indicate his attitude. (Obviously, there is room for disagreement on this one.)

He is suspicious to me does not work for me. These do:

He is suspicious of me. He suspects me.
He looks/seems/appears/is suspicious to me. I suspect him.

 

[Marika33]

No.

He is suspicious to me does not work for me.

That's strange... Google Books has many examples of this kind. (I hope that I used the verb in a singular form is correct since "Google Books" is a resource).

He is suspicious of me. He suspects me.
He looks/seems/appears/is suspicious to me. I suspect him.

What about this?

• He looks suspricious to me, but he may not be suspicious to you.

 

[Piscean]

I wrote (emphasis added);

He is suspicious to me does not work for me.

@Marika33 "He looks suspicious" works. Also: "I'm suspicious of him." Also: "He's behaving suspiciously."
