I looked it up years ago, when Totality was still the VIE's private toy, accessible only via request to KV, and just confirmed it with Totality online. The word 'nuncupatory' occurs only in Cat Island, Cugel the Skybreak Spatterlight, Ports of Call/Lurulu, Night Lamp, Rhialto the Marvellous, Suldrun's Garden, and The Green Pearl.

Thanks for the link--yet another playground for the mind.
