Add new entries here or in the sub-pages

Please add your own entries, in this page or in the appropriate sub-page. Use a quasi-dictionary order, with lowercase treated the same as uppercase and ignoring non-alphanumeric characters (hyphens and such). This means that only alphanumeric characters have any significance in determining order, and that lowercase letters occupy the same ordering position as uppercase (in tie-breaker cases, list lower case first). For example: Ka appears before KA. (This differs from a strict ASCII ordering) Generally speaking, the term alphanumeric refers to anything that consists of only letters and numbers. ... There are 95 printable ASCII characters, numbered 32 to 126. ...

Because of the list's size, acronyms and initialisms beginning with certain characters appear in separate articles.
