an adjective is a part of speech that is used to describe or qualify a noun or pronoun. In this case, 'amazing' is used in order to add more emphasis and heightened emotions to a noun.
When using this word as an adjective, it typically comes before the word it is describing; however, it may appear after the word in some cases (e.g., the view was beautiful amazing). It can be used to describe any subject, quality, or feeling that is beyond expectations.
1. The sunset was an amazing sight to behold.
2. She had an amazing singing voice.
3. The party food was amazing.
In order to maintain its emphasis and validity, it should not be overused; this can make it sound trite or lacking in emotional power. It is best used only when a situation is particularly special or spectacular.
