Okpyeon: Hanja Popup Dictionary

A study tool for Korean learners. Highlight hanja, hanzi, or kanji to read them in Korean, or a hangul word to see its hanja.

Okpyeon is a popup hanja dictionary for Korean learners. Much of Korean vocabulary is built from hanja roots the way English words are built from Latin, so once you know that 國 is 나라 국, the shared root in 국민, 국가, and 외국 becomes visible. Select text on any page and a card appears. Or click the toolbar icon for a sidebar with a search box that stays open across tabs; typing hj in the address bar searches from anywhere. -- CHARACTERS INTO KOREAN -- Select a hanja to get its eumhun (나라 국 for 國), English definitions, and its most common compounds. Simplified Chinese and Japanese shinjitai resolve to the same entries, so those pages work too. -- KOREAN WORDS INTO HANJA -- Highlight a Sino-Korean word in hangul to see the hanja behind it: 국민 becomes 國民, and 자본주의는 in a sentence still finds 자본주의. Words break into their component words and characters, all clickable. -- CHARACTERS SPLIT INTO PARTS -- A character's card shows what it is made of (樂 opens into 幺, 白, 幺, and 木), each part a full entry of its own, and lists the characters it is itself a part of. -- EVERY CHARACTER IS GRADED -- Middle school and High school mark the roughly 1,800 characters of the Korean Ministry of Education list, a natural study list for learners. Advanced and Rare cover everything else, so a glance tells you whether a character is worth your time. -- NO KOREAN KEYBOARD NEEDED -- Typing toddlf with the keyboard still in English finds 생일, and gungmin or gukmin finds 국민. A query that reads both ways shows both. -- BROWSE BY SOUND -- Highlight a single syllable like 국 to list every hanja read that way, most common first. -- FOLLOW THE CONNECTIONS -- Compound lists are complete, a page at a time, and word cards climb upward too: 학생 opens a list of 대학생, 중학생, and the rest. A breadcrumb trail returns to any earlier step. -- SAVED WORDS AND ANKI EXPORT -- Star any card to save it into a folder. Folders export as an Anki text file (settings picks the card fields, folder names become tags) or as a CSV. -- MULTIPLE SPELLINGS AND NATIVE WORDS -- A word with several hanja spellings shows all of them (사기: 詐欺, 士氣, 沙器, and more). Native Korean words return nothing rather than a forced match, and an obscure hanja spelling of a common native word is labelled a rare homograph, not the word's origin. -- WHAT IS INSIDE -- 9,469 hanja characters with readings, eumhun, definitions, levels and compounds 27,627 Sino-Korean words indexed by both hanja and hangul 9,178 character decompositions 3,737 variant mappings covering simplified Chinese and Japanese shinjitai -- PRIVATE AND OFFLINE -- The whole dictionary ships inside the extension, with no network requests or data collection. Saved words stay on your device. -- SOURCES -- Definitions and compounds: English Wiktionary via kaikki.org (CC BY-SA). Variant mappings: Wiktionary and Unicode Unihan. Decompositions: BabelStone IDS (public domain). School tiers: the Korean Wikipedia article 대한민국 중고등학교 기초한자 목록 (CC BY-SA 4.0). The Advanced and Rare levels are Okpyeon's own classification.
