South Semitic is a putative branch of the Semitic languages, which form a branch of the larger Afroasiatic language family, found in (North and East) Africa and Western Asia. The grouping is controversial and several alternate classifications supplanting South Semitic have been proposed in recent decades.
Q-D-Š is a triconsonantal Semitic root meaning "sacred, holy", derived from a concept central to ancient Semitic religion. From a basic verbal meaning "to consecrate, to purify", it could be used as an adjective meaning "holy", or as a substantive referring to a "sanctuary, sacred object, sacred personnel."
Shin-Lamedh-Mem is a triconsonantalroot of many Semitic words (many of which are used as names). The root meaning translates to "whole, safe, intact, unharmed, to go free, without blemish". Its earliest known form is in the name of Shalim, the ancient god of dusk of Ugarit. Derived from this are meanings of "to be safe, secure, at peace", hence "well-being, health" and passively "to be secured, pacified, submitted".
Arabic salām (سَلاَم), Maltese sliem, Hebrew šālōm (שָׁלוֹם), Ge'ezsälam (ሰላም), Syriacšlama (pronounced Shlama, or Shlomo in the Western Syriac dialect) (ܫܠܡܐ), Mandaicšlama (ࡔࡋࡀࡌࡀ) are cognate Semitic terms for 'peace', deriving from a Proto-Semitic*šalām-.
