What is the name given to a specialist of the history of language?
Such a person is a specialist in language history, or a linguistic historian.
Distinguished throughout history, the the proud and noble given name "Alfi" derives from the Old English language word "aelf", meaning "elf", and "raed", meaning "counsel"; hence, "diplomatic and wise counselor, elf counsel". The Teutonic language ascribes the meaning of "supernaturally wise" to the given name "Alfi".
I know this sounds too simple, but after taking a java course in highschool and being taught its history (programming is great but history...torture), anyway, the java language was originally going to be called OAK, but its creators realized that that name was already taken, so after getting a cup of coffee, they knew the name. I got this information from a textbook not a teacher or internet site, so it IS reliable. Good luck…
