Positive adjectives are a class of adjectives that describe a noun using positive emotions such as love, peace and amusement. Keep in mind that these emotions are nouns therefore they must be adjusted to change them into adjectives by adding the appropriate suffixes. Peace becomes peaceful, love becomes loving or lovely and amusement becomes amusing.
Positive adjectives are usually used to make a subject, place, situation or person come across as pleasant and enjoyable. They are very useful in creative writing when an author wants to make the scene that is being described feel happy and relaxed, or to portray a character's good qualities.
