CJK languages do not use spaces when dealing with text containing mostly Chinese characters and kana. In Japanese, spaces may occasionally be used to separate people's family names from given names, to denote omitted particles (especially the topic particle wa), and for certain literary or artistic effects. Modern Korean, however, has spaces as an essential part of its writing system (because of Western influence), given the phonetic nature of the hangul script that requires word dividers to avoid ambiguity, as opposed to Chinese characters which are mostly very distinguishable from each other. In Korean, spaces are used to separate chunks of nouns, nouns and particles, adjectives, and verbs; for certain compounds or phrases, spaces may be used or not, for example the phrase for "Republic of Korea" is usually spelled without spaces as rather than with a space as .
