In languages which use the Latin, Cyrillic, and Arabic alphabets, as well as other scripts of Europe and West Asia, the word divider is a blank space, or whitespace.However, not infrequently in inscriptions a vertical line, and in manuscripts a single (·), double (:), or triple (⫶) interpunct (dot) was used to divide words.This practice was found in Phoenician, Aramaic, Hebrew, Greek, and Latin, and continues today with Ethiopic, though there whitespace is gaining ground.Ancient inscribed and cuneiform scripts such as Anatolian hieroglyphs frequently used short vertical lines to separate words, as did Linear B.In the modern Hebrew and Arabic alphabets, some letters have distinct forms at the ends and/or beginnings of words.
