대학교

university (four-year)
🎓🏫 大學校 = big + learning + school: dae (big) + hak (study) + gyo (school)
Three hanja stack up: 대 (大, big), 학 (學, learning), 교 (校, school). Drop the last syllable and 대학 is college in general; swap the first and you get 고등학교 (high school) and 중학교 (middle school), so 학교 = school is the reusable core.
