Don’t forget to brush your teeth in Korean 🇰🇷

Sentence info.

The sentence breaks down as follows:

• "이" is a noun meaning “tooth” (and by context, it implies “teeth”).
• "을" is the object marker attached to "이."
• "닦는" is the modifying (attributive) form of the verb "닦다" (“to brush” or “to clean”), turning it into an adjective that describes the following noun.
• "것" means “thing” or “act,” so "닦는 것" means “the act of brushing.”
• The second "을" marks "닦는 것" as the object of the following verb.
• "잊지마십시오" is the formal negative imperative form of "잊다" (“to forget”), meaning “don’t forget.”

Romanized, the sentence is:
"I-reul dakkneun geos-eul ijji masipsio."

Tips to remember:
• Notice how the verb in its modifying form ("닦는") is used before a noun ("것") to specify which action should not be forgotten.
• Remember that marking the object twice (once for “tooth” and once for “the act”) helps clarify which part of the sentence is being negated by the imperative.
• Practice by replacing "닦다" with another verb in its modifying form to see how actions become subjects of remembrance.

Alternate ways to say “Don't forget to brush your teeth”:
• "양치하는 것을 잊지 마세요."
 Romanized: "Yangchi haneun geos-eul ijji maseyo."
• "치솔질하는 것을 잊지 마세요."
 Romanized: "Chisoljilhaneun geos-eul ijji maseyo."
• "양치 잊지 마세요."
 Romanized: "Yangchi ijji maseyo."

Each alternate uses a slightly different term for “brushing your teeth” (양치 and 치솔질) and a slightly less formal ending (마세요) while conveying the same reminder.
