Illiteracy means when a person cannot read and write and does not have any knowledge about the subject. When a human being can not read what is written and can not write anything it means they are illiterate. We can say illiterate people are those who are not educated at all or are very less educated. A person can be called illiterate even if they go to school, it is the case when they do not pay attention and lack the knowledge of reading and writing. An illiterate person can never be successful as they do not have even basic knowledge about anything. In this competitive world where 80% is considered as an average percentage, you can think about what will happen to the people who do not even know how to read and write. Illiteracy is a big problem, a country can never be developed if they have a large proportion of illiterate people. Illiterate people generally live in poverty and have health problems because they do not know what is written on the instructions, they basically can’t live a proper life. They have to be dependent on others to tell them what is written and if they are required to write something, they have to make someone else write for them. Illiteracy can prove to be harmful to any country. The Government of the country should do every possible thing to make everyone literate.
