All: Translation: Update ko.po (#2986)

* Translation: Update ko.po

* Update README.md

Both the words ‘한국어’ and ‘한국말’ are composed of two meaning blocks : Korean + language.

어, which can be written in the Chinese character 語, means “language”, and 말, which is a native Korean word, also means “language”. So basically 한국어 and 한국말 are the same meaning, but I’d say 한국어 is a little more formal word while 한국말 is a more colloquial word.

‘어’ can be found in many other language names, but ‘말’ is not so commonly used other than in the word ‘한국말’ or ‘우리말(uri mal - ‘our language’, which is a word that Korean people use to mean ‘Korean’).

Here are some examples:

English = 영어
Chinese = 중국어
Japanese = 일본어
Arabic = 아랍어
Spanish = 스페인어
French =  프랑스어
Latin = 라틴어
Russian = 러시아어
