Here are some examples:
* "I love the taste of chocolate." (Here, "taste" refers to the sensory experience.)
* "The wine has a fruity taste." (Again, "taste" describes the sensory experience.)
* "She has good taste in clothes." (Here, "taste" refers to a preference or style.)
However, "taste" can also be a verb:
* "Taste the soup and tell me if it needs more salt." (Here, "taste" is an action.)
So, the part of speech depends on how it's used in a sentence.
