After all, we all know the sky is grue, right?

毕竟，们都知道天空是阴沉的，对吧？

So you have many languages that have a term to denote both green and blue and typically we call this a grue term.

因此，许多语言都有语来表示色和蓝色，们称之为蓝色语。

Languages that don't have a separate word for blue often group green and blue together in one category, which linguists call grue.

没有单独的蓝色词的语言将色和蓝色归为类，语言学家称之为 grue。

For example, there are actually enough cultures around the world that don't distinguish between green and blue that researchers in this field usually just call them by their couple name: grue.

例如，实际上在世界很多文化中，是不区分色和蓝色，该领域的研究人员用它们的结合词来称呼：蓝。
