I have read a lot of quite conflicting explanations of when and exactly why the Spanish stopped using a word deriving from "sinister", the Latin word for the left, and instead decided to use a pre-Roman (Basque?) word, izquierda. Evidently it is because "sinister" had developed "evil" or "ill" connotations, but is there actually any evidence when this happened? Did Vulgar Latin speakers in what is now Spain ever use "sinister", or did the population refuse to take up the word because the superstitions already existed? I appreciate there may be no evidence either way but it does interest me - especially whether the word "sinister" was dropped because Christians thought it meant the Devil, or if it happened in pre-Christian times Thank you!!
