The earliest signs of spacing between words appear in Latin, where it was used extremely rarely in some manuscripts and then altogether forgotten. The earliest Greek script also used interpuncts to divide words rather than spacing, although this practice was soon displaced by the scriptura continua. Ancient Hebrew and Arabic, while they did not use spacing, used word dividers partly to compensate in clarity for the lack of vowels. Spaces were not used to separate words in Latin until roughly 600–800 AD. Modern English uses a space to separate words, but not all languages follow this practice. Whitespace characters include spaces of various widths, including all those that professional typesetters employ. Ĭomputer representation of text eliminates all mechanical and physical limitations in any sufficiently advanced character encoding environment (such as Unicode), where spaces of various widths, styles, or language characteristics (different space characters) are indicated with unique code points. Following widespread acceptance of the typewriter, some spacing, and other typewriter conventions, which were based on the typewriter's mechanical limitations, have influenced professional typography and other designers of printed works. Most typewriters have only one width of space, obtained by pressing the space bar.
The typewriter, on the other hand, can accommodate only a limited number of keys. Typesetting uses spaces of varying lengths for specific purposes. Conventions for spacing vary among languages, and in some languages the spacing rules are complex. In writing, a space ( ) is a blank area that separates words, sentences, syllables (in syllabification) and other written or printed glyphs (characters).
