Subscript and Superscript - Uses

Uses

A single typeface may contain sub- and super-script glyphs at different positions for different uses. The four most common positions are listed here. Because each position is used in different contexts, not all alphanumerics may be available in all positions. For example, subscript letters on the baseline are quite rare, and many typefaces only provide a limited number of superscripted letters. Despite these differences, all reduced-sized glyphs go by the same generic name of subscript and superscript. Note that the terms subscript and superscript are synonymous with the terms inferior letter (or number) and superior letter (or number), respectively.
