INITIAL, also initial letter, point.
1. The first LETTER of a WORD, usually capitalized in a proper NAME: the L of London, the G, B, S of George Bernard Shaw. The practice of using initials or POINTS in handwriting and print has encouraged the growth of such ABBREVIATIONS as symbols, formulas, INITIALISMS, and ACRONYMS: for example, a stands, among others, for acre and are (units of land measurement); e.g. stands for LATIN exempli gratia for the sake of an example; BBC for British Broadcasting Corporation; NATO for North Atlantic Treaty Organization.

2. The large ornamental letter at the start of a page or chapter, especially in an illuminated manuscript.
