Southern Ward vs South Ward. Volo’s Waterdeep Enchiridion contradicts Volo’s Guide to Waterdeep. Times change, fashions change, lingo changes. In this case, it's a generational thing in Waterdeep. So if you happen across old, white-haired Waterdhavians, stick to "South Ward." If you're talking with anyone who looks young: "Southern Ward" (except nobles, who shun change).
