Literacy should probably be defined like this: the person can read and write their language as well as they can speak and listen. Illiterate people possess language, just not reading and writing. Being able to read, write and think deeply, analytically and critically is setting the goalposts beyond literacy. (I understand it's hard to draw hard lines. Literacy affects the degree of language acquisition. People who become literate acquire more language in so doing than people who remain illiterate.)
