Sol  "the sun," c.1450, from L. sol "the sun," from PIE *s(e)wol-, from base *saewel- "to shine, the sun" (cf. Skt. suryah, Avestan hvar "sun, light, heavens;" Gk. helios; Lith. saule; O.C.S. slunice; Goth. sauil, O.E. sol "sun," swegl "sky, heavens, the sun;" Welsh haul, O.Cornish heuul, Breton heol "sun;" O.Ir. suil "eye"). The PIE element -*el- in the root originally was a suffix and had an alternate form -*en-, yielding *s(u)wen-, source of Eng. sun (q.v.).

Asylum  c.1430, from L. asylum "sanctuary," from Gk. asylon "refuge," neut. of asylos "inviolable," from a- "without" + syle "right of seizure." So lit. "an inviolable place."
