Silver is the language of Silver Rain Republic nationals in the area of the city of Duirt. It is a rough language with a lot of words and sayings related to weather, the ocean and ships. Silver does not have words for left and right, which originate from the speaker, but only cardinal directions which apply generally.

Silver is well known for its excessive list of highly descriptive and very explicit curses. Thus, the expression "silver-tongued" has come to mean "someone who speaks a lot of profanities".
