space (punctuation)

In writing, a space ( ) is any empty (non-written) zone between written sections. However, the term is usually used to refer to an empty zone used for interword separation (interword space) or separation between punctuation and words. Conventions about the presence and size of interword and intersentence spaces vary from language to language, and in some cases may be quite complex. Many different space characters are available in computing character sets for representing spaces of different sizes and meaning.
