think positive vs. think positively.

[Sweetpumpkin]

Hi,

Please give a loot at those two sentences:

1) Let's try to think positive.
2) Let's try to think positively.

I think 1) and 2) are both right, although 1) would be used more. I think 1) is not grammatically right because think is a verb and a verb cannot be modified by adjectives like positive. However, it is widely used and that's why we cannot say it's wrong. What do you think?

Thanks,
sweetpumpkin

Dictionary doesn't say that 'positive' is an adverb but it says 'positive' is 'the primary form of an adjective or adverb'. What is the primary form?

Am I thinking 'positive' (or 'positively') here? :)

I think you're right. "Positively" would be more logical because it must be an adverb. However, it is a "fashionable" expression, so that those who use it probably use it colloquially, where grammar is not very strict. To "think positive" is said often indeed.

Positive as the "primary form of an adjective or adverb" is a technical term of linguistics.

"Great" is called the positive of great, the "normal form" of it.
"Greater" = comparative.
"Greatest" = superlative.
