conc▪ The word seems to be a f. nsb-adj. derived from a *sulām, which however does not exist, nor does the word seem to have any cognates in Sem. Given that a semantic relation between the main values that are known in Sem for the root ↗SLM can hardly be found, the etymology of sulāmiyyaẗ, like that of its ‘sister’ with identical meaning, ↗sulāmà, remains obscure so far.
▪ Should one consider a transfer of meaning from ↗salam_2 ‘(kind of) acacia’ to the digital bones that look like small twigs of a tree? Perhaps also the other obsolete terms of plants mentioned s.v. salam_2 have to be studied as possible origin.
