All 1,087 characters › — or read why hanja is worth an hour if this is the first one you have opened.
Hanja spellings, word meanings and TOPIK grades from the 국립국어원 한국어기초사전, used under CC BY-SA 2.0 KR.
The reading 전 is derived from the alignment between these words' Hangul and their hanja spellings, not taken from a character dictionary — which is also why no 훈 is shown.
