Hint: The question requires us to write the abstract noun of a given word. There are two types of nouns: abstract and concrete. Concrete nouns have a physical presence that you can feel with your five senses. Intangible objects such as behaviours, emotions, principles, ideas, and attributes are referred to as abstract nouns.
Complete step-by-step answer:
A noun that conveys an intangible concept such as an emotion, a feeling, a quality, or an idea is known as an abstract noun. An abstract noun, in other words, does not refer to a physical entity. It can help to think of an abstract noun as a term that describes something you can't see, hear, touch, smell, or taste (i.e., something you cannot perceive with one of your five senses).
For example – consideration, parenthood, belief, anger, energy, failure, faith, fear, freedom, friendship, generosity, gossip, happiness, hate etc.
Example of Abstract noun in sentences:
The education of children should be stressed upon. (Abstract noun: education)
The truth will always come out sooner or later. (Abstract noun: truth)
Anger should be controlled and worked upon to become better. (Abstract noun: anger)
Now the abstract noun of “just” will be “justice”. Justice refers to the quality of being just or righteousness. We cannot see, hear, touch, smell or taste justice hence it is an abstract noun.
Thus the correct answer is ‘Justice’.
Note: Abstract nouns should be differentiated from concrete nouns. There may be situations where it can be ambiguous to identify the noun. For example, we cannot see “laughter” but we can hear it hence it is a concrete noun and not an abstract noun.
Nouns with the following suffixes are often abstract:
-tion, -ism, -ity
-ment, -ness, -age
-ance, -ence, -ship
-ability, -acy
