What does illiteracy mean?
Illiteracy is the state of being unable to read or write, especially when a person has not acquired basic literacy skills. In contemporary public discussion, the word often appears in education, development, and social-policy contexts, where it identifies a serious barrier to employment, civic participation, health information, and personal independence. The term can also describe broader educational disadvantage rather than the complete absence of reading and writing. Discussion of illiteracy may distinguish formal illiteracy from functional illiteracy, which refers to people who can read or write in a limited way but cannot use those skills effectively for everyday information and tasks. Although the vocabulary is often blunt, accuracy requires distinguishing a lack of access to instruction from an individual's ability or willingness to learn. Illiteracy is therefore both a straightforward description of literacy skills and a term with substantial social, educational, and economic implications.

Where does illiteracy come from?
Illiteracy was formed in English from illiterate and the noun-forming suffix -acy. Its deeper roots lie in Latin illitteratus, meaning 'unlettered', which was formed from in- and litteratus, meaning 'lettered', from littera, 'letter'. English words such as literate, literacy, literal, and letter belong to the same Latin-derived family.
