What is defined as the ability to read, write, and function in a given language?

The ability to read, write, and function in a given language is best defined as literacy. Literacy encompasses not only the basic skills of reading and writing but also the capacity to engage with the language in practical, meaningful ways. It is a fundamental skill that enables individuals to access information, communicate effectively, and participate fully in society.

While fluency refers specifically to the smoothness and ease of language use, comprehension focuses on understanding the meaning of text, and numeracy pertains to the ability to work with numbers and mathematical concepts, none of these encompass the broader and more encompassing definition of literacy. Literacy is essential for education and personal empowerment, making it a cornerstone of effective communication and knowledge acquisition in any language.
