中文泛指汉语语族及其书写系统。现代汉语（普通话）是世界上使用人数最多的语言。使用人数已达到十七亿以上。在中国，大陆使用简体汉字，港澳台地区使用繁体汉字。海外华人地区多使用繁体汉字。汉字的起源，有传说中的仓颉造字。我们现在能够确认距今约3000多年的甲骨文已经是非常成熟的文字体系，于1899年被发现。可以考证的汉字发展经历了甲骨文、金文、小篆、汉隶、楷书、行书、草书等过程，可以划分为两个大阶段。从甲骨文字到小篆是一个阶段；从秦汉时代的隶书以下是另一个阶段。前者属于古文字的范畴，后者属于近代文字的范畴。大体说来，从隶书到今天使用的现代汉字形体上没有太大的变化。从汉字跟汉语的关系看，汉字是一种语素文字。汉字代表的是汉语里的语素。汉字有独体字与合体字的区别。从构造上讲，合体字比独体字高一个层次 。合体字可以分成以下 3 类：①形声字。由表示意义的形旁和表示读音的声旁两部分组成；②合体会意字。是会合偏旁的字义来表现整个合体字的意义；③合体记号字。这种合体字的偏旁既不表意，也不表音。跟拼音文字相比，汉字最大的长处是能够超越空间和时间的限制，汉语是全世界唯一的三维文字，既有表音，又有表意，还有表形，是现阶段人类文明中最稳固也是最先进的语言体系 。
