Hermes is a WoW addon that lets you talk to the other faction with manageable level of comprehension loss. More information here: https://www.curseforge.com/wow/addon...s-commonorcish

Aside from porting the addon from Classic to WotLK, I have also added the command /phermes, which shows in chat what the other faction would see but it does not say anything; that way, you can correct the text before you actually say it.
