The other day I was wondering about the word surname. What is the sur-? prefix. The etymology, while perhaps not immediately obvious, is quite straightforward; the sur- is a French variation on the Latin super, meaning above or beyond. It comes to us, like many French roots, from the Normans. So a surname is one’s second or higher name, and the word dates to the fourteenth century.
But there are other sur- words, some like surname, borrowed whole from French (Anglo-Norman surnum, early fourteenth century), while others have been formed in English:
surcharge, an additional charge, originally a verb (1429) borrowed from the Old French surcharger and turned into a noun by 1601
survive, to live beyond or after (1473), from the Anglo-Norman survivre, which was formed from the Latin vivere, to live
surpass, to go over or beyond (1588), from the French surpasser.
