An adverb usually modifies a verb and tells more about the action in a sentence. However. sometimes, an adverb modifies an adjective. Here are some common adverbs that tell more about an adjective:
more, less, very, really, exceptionally, extremely, rather, quite
These adverbs are sometimes called intensifiers because they intensify the adjective – or make it stronger.
Look at these two sentences. In the first, the adjective pretty tells more about Mary, the girl. The adverb extremely intensifies the adjective pretty.
Mary is a pretty girl.
Mary is an extremely pretty girl.
I ate a bowl of really good ice cream after dinner.
We took a very difficult test in math.
That was a rather disappointing movie.
Some adverbs are used as intensifiers to modify an adjective.
It’s your turn. Find the intensifier adverb in this sentence: Jim is an extremely skilled baseball player. Did you figure it out? Good for you!
