Romanization is a day-one crutch that blocks Hangul fluency. How to quit without freezing progress.
Politeness lives on the verb
Learners sometimes 요-bomb every noun. Politeness lives on the predicate ending, not free-floating 요.
저는 is not gendered
저는 / 나 are not gendered. Focus on speech level and role nouns instead of inventing gendered “I am.”
Spacing before 요
Where spaces go with 요 and polite endings so Hangul writing looks native.
반말 timing
When casual speech is welcome and when dropping 요 makes you sound rude.
Verb at the end
Subject-object-verb order: stop ending sentences with nouns the English way.
Null subjects
Null subjects are natural in Korean, but over-dropping makes you unclear and under-dropping sounds stiff.
Batchim linking
Final consonants link into the next syllable in speech: reading Hangul blocks ≠ careful spelling pronunciation.
Time + 에
Clock times and many calendar words take 에; duration often does not. Fix the “Monday go” mistake.
“Only” with negatives
밖에 + negative means “only.” It is not an English double-negative puzzle if you learn it as a unit.
Descriptive verbs conjugate
크다/좋다 conjugate like verbs. Not English “be + adjective.” Stop inserting 이다.
Null objects
Korean omits repeated objects; English learners over-specify every 을/를 phrase.
시 vs 분 (number systems)
Telling time: native numbers for 시, Sino-Korean for 분: the classic beginner mix-up.
반말 too early
Why dropping 요 with new acquaintances can sound rude and how to wait for an invitation.
Double subject marking
Topic and subject particles are not stacked on one noun the English way learners invent.
Object particle with adjectives
Descriptive verbs usually take 이/가 subjects, not English-style “object” marking.
필요하다 particles
시간이 필요해요 not 시간을 필요해요: particle choice with 필요하다.
ㅂ irregular
ㅂ irregular adjectives: 춥다 → 추워요 and common weather mistakes.
르 irregular
르 irregular: 모르다 → 몰라요 and other high-frequency traps.
Time-place-object-verb
SOV order with time/place expressions: stop ending sentences with nouns like English.
Question word placement
Korean question words sit where the answer would sit; fronting every 뭐 like English is optional, not required.
Dropping 저 too much
Korean drops subjects, but beginners over-drop and become unclear. Or under-drop and sound stiff.
