Literacy, broadly defined as the ability to read, write, and engage critically with written information, has evolved from a narrow focus on alphabetic skills to a multifaceted concept encompassing social, cultural, and technological dimensions. Historically linked to functional needs such as governance and trade, modern definitions—such as UNESCO’s emphasis on interpreting and creating written materials across contexts—reflect its expanded role in education, empowerment, and digital participation.
Authors like Mihai Nadin explore literacy as a universal medium shaping thought, culture, and communication, while others highlight its role in democratizing knowledge and promoting critical awareness. Contemporary frameworks, from multiliteracies to digital proficiency, underscore literacy’s dynamic interaction with societal change, revealing it as both a foundational skill and a driver of personal and collective transformation.
