Did not sleep in Korean 🇰🇷

안 잤어 info.

Tips to Remember the Word:
• “자다” means “to sleep.” Remember that to form a negative, you add “안” before the verb.
• The past tense “잤어” comes from dropping the “아/어” from “자다” and adding “았어”–a common way to form past informal endings. So, “안 잤어” literally means “did not sleep.”
• Visualize “안” as a barrier stopping sleep (자) from happening.

Explanations:
• “안 잤어” is an informal and casual way to say “did not sleep.” It’s used among friends or in relaxed contexts.
• The verb stem “자–” becomes “잤–” in the past tense when you describe an action already completed.
• The structure consists of the negative marker “안” followed by the verb in its past form, resulting in “안 잤어.”

Other Words with Similar Meaning:
• “잠 못 잤어” – This phrase translates to “couldn’t sleep” (adding the noun “잠” for “sleep”).
• “잠을 안 잤어” – Including the object marker “을” with “잠” (sleep) achieves the same meaning, “did not sleep.”
