Abstract and concrete are opposite concepts, many times we just know what they mean, but don’t really understand them. So today let us get to know them again and have a clearer and deeper understanding of them.


An abstract is a brief summary of one or more things, there are two important points here:

  1. From one or more things
  2. Find out the basic common characteristics

For Examples:

  1. Man is an abstract of people who have common male characteristics
  2. Human is an abstract of Man and Woman


A concrete is a definite or specific of an abstract, which means a concrete is an abstract that is concretized. For examples:

  1. You are a concrete of Human
  2. Man or woman is a concrete of Human
