Answer:
Adjective.
Step-by-step explanation:
In English language, a noun can be defined as a word used to refer to a person, place, animal, idea, feeling or thing. Therefore, a noun is considered to be a naming word.
There are four (4) major types of nouns and these includes;
I. Abstract nouns.
II. Collective nouns.
III. Common nouns.
IV.Proper nouns.
An adjective is one of the parts of speech in English language and it can be defined as a word that qualifies or describes a noun in a sentence. Some examples of an adjective are big, small, happy, tall, short, fat, rambunctious, etc.
When a suffix "ful" is added to a noun, the part of speech it will become is an adjective. For example, cheer becomes cheerful, play becomes playful, joy becomes joyful, beauty becomes beautiful, etc.
