A neologism for “bar, barrier” coined by Orondil on 2021-09-24 in the Vinyë Lambengolmor Discord Server (VLDS), related to ✶stama- “bar, exclude” (UT/282). Luinyelle proposed ᴺQ. sámo [þ] on 2023-01-11 of similar derivation, but I prefer Orondil’s neologism since Luinyelle’s conflicts with partially attested ✱sámo [þ] “helper”, a hypothetical element of Rómestámo “East-helper” (PM/385).
#sámo (þ) noun "helper", tentatively isolated from Rómestámo "East-helper", q.v. When initial, st- would normally simplify as s-, for archaic þ-.
