The term "illiterate" refers to individuals who lack the ability to read and write. This condition can result from various factors, including inadequate education, socio-economic challenges, or limited access to learning resources. Illiteracy can significantly impact a person's ability to communicate effectively and access information. Illiteracy is a global issue, affecting millions of people, particularly in developing countries. Organizations like UNESCO work to promote literacy programs and improve educational opportunities. Addressing illiteracy is essential for personal empowerment and economic development, as it enables individuals to participate more fully in society.
