Youjian

Youjian is a Mandarin Chinese term most often encountered as the word for mail, particularly electronic mail. It is written as 邮件 in simplified Chinese and 郵件 in traditional Chinese; the characters combine mail or post (邮/郵) with an item or piece (件). In contemporary usage, youjian usually denotes email rather than conventional postal mail, which is more commonly called 信件 (xìnjiàn). For example, 发送一封邮件 means to send an email, and 我收到了你的邮件 means I received your mail.

In IT and communications contexts, youjian appears in phrases such as 发送邮件, 收取邮件, and 电子邮件 (electronic mail). The term also shows up in everyday speech, computer user interfaces, and formal writing.

Beyond its function as a common noun, youjian can be a transliterated sequence within personal names or brand names, though it is not a typical standalone given name. If used as a name, its meaning depends on the chosen characters; possible readings could be you with various second characters (for example 友建, 佑健, 语健), among others. The pronunciation remains you-jian regardless of the characters.

Because pinyin representations are shared by different terms, youjian may appear in non-Chinese contexts as well, and its intended meaning should be inferred from surrounding text.
