to this was Spain's conquest by the Moors in the Middle Ages, leading to another vector for creating doublets (Latin to Arabic to Spanish). Welsh Welsh contains many doublets of native origin, where a single Indo-European root has developed along different paths in the language. Examples of this are: "boiled, boiling" and "enthusiastic" from Proto-Indo-European * "to boil, brew" "bed" and "place" from Proto-Indo-European * "to lie (down)" "spring", "dawn" and "swallow (bird)" from Proto-Indo-European * "spring" "breath" and "soul" from Proto-Indo-European * "to breathe" "mead" and "drunk" from Proto-Indo-European * "honey, mead" In addition to native doublets, Welsh has borrowed extensively over the centuries, particularly from Latin and English. This has led to many more doublets in the language, including many from Latin that entered Welsh via English borrowings. Examples include: "God", "day" (both native), "Thursday" (Latin) and "journey" (Latin via French via English) from Proto-Indo-European * "to be bright; sky, heaven" "yoke (pulling frame)" (native) and "yoga" (Sanskrit via English) from Proto-Indo-European * "to join, to tie together" "free" (native), "argument" (Germanic via Latin and French via English) and "friend" (English) from Proto-Indo-European * "to love, please" "Scotland" (Irish) and "Alps" (Latin via English) from Proto-Indo-European *albʰós "white" "needle", "to spin" (both native), "nerve" (Latin via English) and "neuro-" (Greek via English) from Proto-Indo-European * "to spin, sew" See also Reborrowing Cognate, specifically, those within the same language False friends that may develop in the same way References External links Historical linguistics Types of words
