Calling someone a Suy' is quite derogatory, comparable to using the word "pig" in Federation Standard. Mistakenly calling someone a Suy ("merchant") when the intent is to be insulting and call him or her a Suy' will have the effect of making the speaker appear to be foolish and, therefore, weak and hardly in a position to be ridiculing someone else. Furthermore, the speaker may inadvertently offend a nearby merchant.
