Re: Vocab
The wikipeidia article is weird, I think it's broken.
In the 'introduction' of the article, it says 1972 is the first recorded usage of chaebol, but in the actual 'Entymology' section it says the 1980's.
The 1972 date is referenced from merriam-webster dictionary reference [2]), whereas the entymology is from the Oxford dictionary (reference [1]) that doesn't include the date in its reference. So not sure where the author of the wikipedia article got 1980's from, as that date is in neither of the supplied dictionary references. but the 1972 one it.
