Korean

Hangul was designed in 1443 under King Sejong as a from-scratch alphabet, with letter shapes that visually represent the position of the tongue, lips, and throat for each sound. Letters group into syllable blocks (so 한 stacks ㅎ + ㅏ + ㄴ visually). Most learners can read Hangul within a day or two of focused study, which makes Korean unusually accessible at the script stage.

Korean has seven traditional speech levels marked through sentence endings, ranging from very formal-honorific to intimate-casual. Modern usage focuses on three or four. The level you choose depends on the listener's age, status, and your relationship — getting it wrong is socially loud. The same statement, rendered across levels, can sound everything from royal-court formal to bratty.

Possibly, but unproven. The two languages share striking grammatical similarities — SOV order, particles, agglutination, honorific systems — but the core vocabulary doesn't show systematic correspondence required to demonstrate a genealogical link. Most contemporary linguists treat Korean and Japanese as language isolates whose resemblances may come from contact rather than common descent.

Rarely in everyday text. Hangul replaced almost all Chinese-character (hanja) use in the 20th century, especially in North Korea, which abolished hanja entirely. South Korea sometimes uses hanja in newspapers, academic writing, and to disambiguate Sino-Korean homophones, but daily reading is fully Hangul. Korean vocabulary, however, is roughly 60% Sino-Korean in origin.

Hangul is fast. The grammar takes longer — particles instead of word order, an honorific system to internalize, verb endings that encode tense, mood, and politeness all at once. Vocabulary has limited overlap with English. Most learners describe a steep first six months followed by a long but rewarding climb through the politeness system.
