What is the abstract noun of “great”?

Hint: Abstract and tangible nouns are the two categories of nouns. Intangible concepts—things that can't be perceived with the five senses—are denoted by abstract nouns. By adding the suffix "ness" to the word "great," we may create an abstract noun.

Complete answer:
A quality or more about something we can only think about, not see or touch, is an abstract word. Uncountable emotions include courage, pleasure, horror, and love. Because they are countable, some abstract nouns, such as joke and failure, may have a plural form. Only a few examples are beauty, courage, friendship, intellect, truth, love, hatred, liberty, slavery, talent, wit, knowledge, and so on.

Abstract nouns are terms that refer to non-concrete objects. You can't see, smell, taste, hear or touch an abstract term since your five senses can't detect it. An abstract noun is essentially a characteristic, a notion, an idea, or even an event.

Adjectives like kid, childhood, and happiness, as well as verbs like know, knowledge, can be used to create abstract nouns. Proper nouns such as the Taj Mahal, the Twin Towers, the Empire State Building, and others are not abstract nouns.

Thus, the abstract noun of great is greatness. Great denotes a size, quantity, or intensity that is significantly greater than average. The attribute of being great is referred to as greatness.

Thus, the abstract noun of great is greatness.

Note: Concrete and abstract nouns are not interchangeable and should not be used interchangeably. Concrete nouns have a tangible existence that your five senses can detect. Consider the difference between an abstract term, such as anger, and a concrete noun, such as a chair. A chair can be touched and seen, but rage cannot be touched or seen.
