Currently there is no specification on the Kathar page that Ritualistic She'llaq can only be used for rituals and not common conversation. Since Ritualistic She'llaq is later specified to be only for rituals (in the language section) it easily leads to lost time explaining and justifying in game to players who might not know that it can only be used for ritualistic sacrifice. Fixing this could be as easy as adding a caption.
Except the ritualistic part of She'llaq is specified when the Languages box calls it 'Ritualistic She'llaq'. It's simple reading comprehension, not something that requires a disclaimer or a subnote. Even further, it isn't just for sacrifices. The numerous Kathar celebrations like the Carnage Feast of Thräl’laniir are very clearly ritualistic in nature. It doesn't take much hard thought to draw a line from the ritualistic language to the rituals themselves.
I just thought that "Ritualistic She'llaq" means used for rituals, not that it is only used for rituals, but that that is what it is often used for.
