Definition: Adjectives are words that describe, classify or modify something. They can be used to define the qualities, characteristics, strengths, weaknesses, similarities, differences or other attributes of an object, person, place, thing or idea. For example: - The adverb 'quickly' is a word that describes a process or state of being quickly. - The adjective 'beautiful' describes something in terms of its appearance and beauty. - The prepositional phrase 'underneath the moon' describes what is below a certain object, person, place, thing or idea. Understanding how adjectives work helps us understand complex sentences by breaking them down into simpler parts that can be combined to form more coherent thoughts.
