名无固宜，约之以命，约定俗成谓之宜，异于约则谓之不宜。
释义Explanation
这句话指出，事物的名称并非天然就合适，而是人们通过共同约定来命名；一旦约定形成习惯，就被认为是恰当的，违背约定则被认为不恰当。它揭示了语言符号的社会契约属性，强调语义并非固定不变，而是依赖群体共识。现代社会中，术语规范、网络流行语和品牌命名都遵循这一逻辑，提醒我们重视沟通中的共识建设。
The quote states that names have no inherent appropriateness; they are created through collective agreement. Once a convention becomes established and customary, it is deemed fitting; what deviates from that convention is deemed unfitting. This reveals the social-contract character of language symbols, emphasizing that meaning depends on group consensus rather than natural correspondence. In modern life, technical terminology, internet slang, and brand naming all operate on this principle, reminding us to prioritize consensus-building in effective communication. Thus, shared recognition—not an external standard—determines linguistic validity.
使用场景Usage
在日常沟通或产品开发中，团队常需要为新功能、新概念命名。与其反复争论哪个名称“本来就对”，不如先约定一个临时名称，并在使用中逐步固化。当成员或用户习惯了这个名称，它便自然具备了指代和沟通功能。这句话提示我们：语言的有效性来自共识，而非某个预设的“正确”答案，达成约定比追求绝对正确更实际。
In daily communication or product development, teams often need to name a new feature or concept. Instead of endlessly debating which name is inherently right, it is more practical to agree on a provisional term and let it solidify through usage. Once members or users become accustomed to it, the name naturally gains referential and communicative power. This saying reminds us that linguistic effectiveness comes from consensus, not from a presumed “correct” answer—reaching agreement is more practical than chasing absolute correctness.
