Evidence for the origin explanationMedium
The definitions in the body of the 2001 collection were compared. The collection also includes previously used words absent from dictionaries. The original older articles re-quoted there were not separately opened, and neither the first use date nor the extent of spread at the time was verified. The pairing of the Korean corresponding name and abbreviation was checked; a guessed English expansion was not supplied.
