Why is this item weird?

Enter a Wikidata item (a Q-number, a wikidata.org link, or just a name). You get a plain-language list of things that look inconsistent or missing, and what to do about each.

Try: Q42, Q64, Q1

These are heuristics, not official constraint reports. An odd item is not always a wrong one: some real people and places break the usual patterns. Check before you edit.
