Does the following sentence have any adverbs? If so, where?: The plane slowly landed.
This sentence could also be written as:
The plane landed.
However, it is possible that we add some description of how the plane landed, as follows:
The plane slowly landed.
Since slowly describes how the plane landed, it is an adverb.
A good rule of thumb for noticing adverbs is that they almost always end in the letter pattern "-ly".
