LogogramIn a written language, a logogram, logograph, or lexigraph (from Greek logo, "word", and gramma "that which is drawn or written") is a written character that represents a word or morpheme. Chinese characters (pronounced Hànzì in Mandarin Chinese, Kanji in Japanese, Hanja in Korean, Hán tự in Vietnamese and Sawgun in Standard Zhuang) are generally logograms, as are many hieroglyphic and cuneiform characters. The use of logograms in writing is called logography, and a writing system that is based on logograms is called a logography or logographic system.
Chinese charactersChinese characters are logograms developed for the writing of Chinese. Chinese characters are the oldest continuously used system of writing in the world. By virtue of their widespread current use throughout East Asia and Southeast Asia, as well as their profound historic use throughout the Sinosphere, Chinese characters are among the most widely adopted writing systems in the world by number of users. The total number of Chinese characters ever to appear in a dictionary is in the tens of thousands, though most are graphic variants, were used historically and passed out of use, or are of a specialized nature.
PinyinHanyu Pinyin (), often shortened to just pinyin, is the most common romanization system for Standard Mandarin Chinese. It is used in official contexts where Standard Chinese is an official language (Greater China and Singapore) as well as by the United Nations and in other international contexts. It is used principally to teach Mandarin, normally written with Chinese characters, to students already familiar with the Latin alphabet.
