Quality
Quality is fitness to use or we can say quality is perception, because all the people in this world will not have a same opinion about same thing, no matter how good that thing is in your point of view. If a thing is fullfilling my needs then I can say that it has quality but that might not be the instance for others as well because others may not like what I like! therefore we make perception about things knowingly or unknowingly.
