* "Qualified" is an adjective, meaning it describes a noun. It doesn't stand on its own as a concept.
* Abstract nouns represent ideas, qualities, or states of being. Examples include love, freedom, happiness, or knowledge.
While "qualified" describes a state of being (having the necessary skills and knowledge), it's not a concept that exists independently. It's a description of a person, a thing, or a skill.
Therefore, there are no abstract nouns in the word "qualified."
