I believe that non-rhoticism is much more recent than the 400 year b.p. date given for the introduction ofn sherbet and its almost immediate variation, sherbert. What I wanna know is, when it came into English did we know to change the French or Italian, whichever it was, initial S back to the original Arabic SH or was that just some ignorant, lazy solecism?

Language Log has given a date for the start of non-rhoticism, but I couldn't find it. Or maybe it was Nuncle zhd.
