In the 뉴에이스 국어사전 included with the iOS/MacOS Dictionary app, I noticed the etymology for the word 함부로
showed:
〔➙ᄒᆞᆫ보로(金三 2:33)>함부로〕
What does the 金三 2:33
mean?
Looking up the same word in Naver, it shows:
어원 : <보로<금강경삼가해(1482)>
I notice the 금
and 삼
in there, so guessing they are possibly related to the 金
and 三
respectively. Is this a way of representing dates, perhaps based on the royal calendar? I've seen things in museums that say something like, "the 3rd year of King Sejeong." Is this related?
