Korean numbers: native vs Sino-Korean usage

About this quiz

What you’ll practice

This quiz trains you to pick the right Korean number system for the context—native Korean (하나, 둘…) or Sino-Korean (일, 이…). You’ll see everyday situations like age, hours/minutes, dates, prices, floors, and counts.

Every question is multiple-choice with 4 options and no timer, so you can think through the rule before committing.

Difficulty and quiz setup

Difficulty is mixed on purpose: simpler “counting things vs dates” items appear early, while trickier edge cases (counters, time expressions, and formal contexts) show up regularly to keep your skills balanced. Choose your preferred question count and difficulty before starting to tailor the session to quick review or deep practice.

Common pitfalls to avoid

Many learners overuse one system everywhere, especially switching incorrectly on time (hours vs minutes) or mixing systems inside a single expression. Watch for context clues like counters, units, and “calendar/numbering” situations.

Native Korean is common with counters for items/people, and for hours in telling time.
Sino-Korean is common for dates, minutes/seconds, money amounts, phone numbers, and numbering (floors, bus routes).
Don’t forget that some counters strongly “pull” one system more than the other.
In time expressions, check whether you’re answering “what hour?” or “how many minutes?”
When you miss one, reread the situation: the context usually reveals the correct system.

How to improve faster

After each attempt, note the context type you missed (time, date, counting, money, numbering) and practice that category again with a shorter set. Repeating mixed difficulty sessions helps you build automatic switching rather than memorizing isolated rules.
