I think I'll have a cold drink than coffee. Someone told me that the meaning of this sentence is that the subject, I, more wants a cold drink than coffee, but I do not agree. Even "than" can't be used with general verbs. Am I right? Or the sentence above is possible? Although I found "than" is used with "different", other than it, I have never found "than" is used with general adjectives or verbs. Or are there more exceptions than I know?

As usual, I need your help to get out of this probelm. Thanks a million in advance.
Rather than means instead of here. I assume you do not thoroughly understand the use of rather than.

I think I'll have a cold drink rather than (= instead of; in place of) coffee.

The sentence above is perfectly good.

Hi, thanks for replying but the sentence I wrote as an example has no "rather". I also agree with your answer but someone told me the sentence without "rather", just with "than" could mean "more want". Is this right?
I had not noticed your sentence did not contain rather. It is incorrect, then. Rather is missing.

we can also say I 'll prefer cold drink to coffee.
