Usage Note: For most of its long history in English, literate has meant only "familiar with literature," or more generally, "well-educated, learned." Only since the late 1800s has it also come to refer to the basic ability to read and write. Its antonym illiterate has an equally broad range of meanings: an illiterate person may be incapable of reading a shopping list or uneducated in a particular field. The term functional illiterate is often used to describe a person who can read or write to some degree but below a minimum level required to function in even a limited social situation or job setting. An aliterate person, by contrast, is one who is capable of reading and writing but who has little interest in doing so, whether out of indifference to learning in general or from a preference for seeking information and entertainment by other means. The meanings of the words literacy and illiteracy have been extended from their original connection with reading and literature to any body of knowledge. For example, "geographic illiterates" cannot identify the countries on a map, and "computer illiterates" are unable to operate computers effectively.
