Translating Korean to English
Korean marks topic and subject separately with 은/는 and 이/가, a distinction English collapses entirely - yet it determines what the sentence is about versus what is new information, which shapes how the English should be built. Korean omits subjects as freely as Japanese, so English has to reinstate them from context. Speech level is encoded in verb endings and vanishes on the way into English, taking the social relationship with it. Word order is subject-object-verb. Korean honorific verb forms can mark respect toward someone mentioned rather than the listener, a distinction with no English equivalent. Sino-Korean and native Korean vocabulary coexist with different registers, roughly the way Latinate and Anglo-Saxon words do in English.

Korean speech levels are detected automatically - formal (합쇼체) input produces more formal English, casual (해체) produces relaxed English.
Korean SOV word order is restructured to natural English SVO without awkward phrasing.
Konglish (Korean-English loanwords) are translated back to standard English naturally.
For K-drama or K-pop related content with cultural references, the AI provides contextually appropriate translations.
Frequently Asked Questions
