I've recently been enjoying a series of word-history videos on the YouTube "alliterative" channel. They're very detailed: https://www.youtube.com/user/Alliterative so if you like this kind of article check those videos out. Although, I have to admit to a certain sadness that comes with being reminded that there's no "correct English," and given enough years the language I speak will be considered archaic or worse.
