Alphabetic or alphabetize describes a listing, sort, or order that is done alphabetically. An ascending alphabetic sort orders text by the first letter of the first word, with 'A' first and 'Z' last. (Other special characters, such as an underscore, are usually ordered to precede 'A.') In the example below, a list of number names has been sorted in ascending alphabetical order.
Example of an ascending alphabetic sort
eight five four nine one seven six ten three two
Example of a descending alphabetic sort
Many programs and tools can also allow you to do a descending alphabetic sort that sorts every word from 'Z' to 'A' in a list of words.
