In punctuation, a word divider is a glyph that separates written words. 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, a convention which is spreading, along with other aspects of European punctuation, to Asia and Africa. However, many languages of East Asia are written without word separation (Saenger 2000).
