This is Everyday Grammar. I'm Kaveh. And I'm Lucija. The other day I was reading an article about the health benefits of vegetables. Fascinating stuff. Bottom line, vegetables are great for your health. Interesting. And great for is also an adjective plus preposition structure. What? English speakers use adjectives in front of nouns or after non-action verbs.
Non-action verbs include words like be, seem, or become. When speakers use adjectives after a non-action verb, they often use a preposition. That is fine with me. All of these adjective and preposition combinations have specific meanings, but they are too many to describe. However, the most common combinations in speaking are adjective plus of, adjective plus for, and adjective plus with.
