![]() Ancient Hebrew and Arabic did use spaces 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. Precision is limited by physical capabilities of output devices. Similarly, word processors can "fully justify" text, stretching inter-word spaces to make all lines the same length (as can mechanical Linotype machines). By drawing each word at a specific starting coordinate, such programs need not "draw" spaces at all (this can lead to difficulties in extracting the correct text back out). For example, SVG, PostScript, and countless other languages enable drawing characters at specific (x,y) coordinates on a screen or page.
