It's Halloween again, and a thought just struck me: why isn't "spooktacular" an official dictionary word? It appears in edited prose, it's certainly in widespread use, and could be clued as something like "n.
a wild party with a haunted-house or horror theme, esp. one given around Halloween. Jocose
." (And of course there's the even more common adjective form.) I'm not saying it's exceedingly common, but I'd at least expect to see it in an unabridged lexicon somewhere.
I guess I'm just asking because I want to know how long the damn word's been in the language. My guess is that it dates to early postwar commercial culture--1946 or so. But unless it shows up in Merriam-Webster with a date next to it, how will I ever know?
