west▪ Any relation to Grk Sêres, Lat Seres, the term used in Antiquity as a name for Chin traders? According to Lokotsch1927#1878, this name derives from Chin 丝儿 (絲兒) sī-ér, composed of sī ‘silk’ and the nominal suffix designating persons, -ér, »common among the inhabitants of the NChin provinces«. From the n.gent. Lat Seres are the name of the country Serica, the adj. seric-us ‘Seric, made from silk’, as n. serica ‘silk dress’. The Lat serica (~ sarica ~ sirica) gave Fr serge, sarge, Prov serga, It sargia, Cat sarja, Span Port sarga, Rum sarecă ‘serge, kind of woolen material, (wiki:) type of twill fabric that has diagonal lines or ridges on both sides, made with a two-up, two-down weave’, Span jergo, Port xergo ‘paillasse, straw mattress’, Span jergon, Port enxergão ‘paillasse’, Span sirgo ‘waste silk’, (Calabr)It siricu ‘silk worm’, Ge Sarsche; Ru sarža, Bulg sarža, Cz sarše, Pol sarza, szarsza ‘type of woolen material’. From Lat seric-um, adj.neutr., ‘silken, made of silk’, are also (mediated by oFr) Engl silk, as well as oSlav šelkŭ ‘silk’ > Ru šëlk, Ukr šołk ‘silk’, Ru (deriv.) šelkovica, šelkovnik ‘mulberry tree’. – It seta, Span Port Prov seda, Fr soie, Ge Seide go back to mLat seta ‘silk’ which is probably short for seta serica ‘Seric hair’, from Lat saeta ‘thick hair, bristle’ and the adj.f. seric-a, described above.
