Sneak: *climbs out of a hole, holding records* o_o Guys... I got sucked into researching the various terms plurals have used over the years for singlets.
Okay, so there's like, a FLURRY of terms that all crop up in my records in 1992: single, single person (SP), singlet... the only terms that I could first find from
other years were singleton (which I could prove appeared by 1991) and singletype (which seems to have come from a lost-to-the-sands-of-time argument on Dark Personalities in 2001 and never really broke containment).
I haven't dug super deeply into single and single person (just because they're such common words, you can't easily just search for them), but here are Mori’s and my quick and dirty notes on singleton and singletype!
