Do you know which of the three sentences listed below is grammatically correct, which is grammatically incorrect, and which is possibly grammatically incorrect?
- Drive slow.
- Be slow.
- Take it slow.
Sentence 2 is correct. The being verb, be, requires the adjective slow to complement it.
Sentence 1 is incorrect. The action verb, drive, requires the adverb slowly to describe it.
Sentence 3 may be correct or incorrect, depending on the context. If I mean that in general you should take a slow approach to life, then Take it slow would be correct. If I mean that you have been taking a specific thing too quickly and you ought to slow down (e.g., your lunch), then Take it slowly would be correct.
Since adjective-adverb confusion plagues most speakers and writers of English, I'll provide additional examples in future posts.
