Korean Grammar-How to Speak Formally About the Past

Welcome back, Korean language learners! 👋

In our previous post, we looked at the informal polite style (-아/어요). Today, we will learn how to form the Formal Polite Past Tense (-았습니다 / -었습니다).

This style is used in formal settings, such as news broadcasts, business meetings, public presentations, military contexts, or when speaking respectfully to someone you don’t know well.

1. Core Structure & Rule Breakdown

To form the formal past tense, you attach -았습니다, -었습니다, or 했습니다 to the verb stem (the verb after removing -다).

💡 The 3 Key Rules

Rule	Condition	Declarative (Statement)	Interrogative (Question)	Example (Base Form → Past Tense)
Rule 1: -았습니다	Stem final vowel is ㅏ (a) or ㅗ (o)	Verb stem + -았습니다	Verb stem + -았습니까?	가다 (to go) → 갔습니다 / 갔습니까? 보다 (to watch) → 봤습니다 / 봤습니까?
Rule 2: -었습니다	Stem final vowel is ANY OTHER VOWEL (ㅓ, ㅜ, ㅣ, ㅡ, etc.)	Verb stem + -었습니다	Verb stem + -었습니까?	먹다 (to eat) → 먹었습니다 / 먹었습니까? 읽다 (to read) → 읽었습니다 / 읽었습니까?
Rule 3: 했습니다	Verbs ending in 하다 (ha-da)	했습니다	했습니까?	운동하다 (to exercise) → 운동했습니다 / 운동했습니까?

2. Past Tense of “To Be / Not To Be” (이다 / 아니다)

• Noun + 이었습니다 / 였습니다(was / were)
  • Ending in Consonant: 학생 + 이었습니다 → 학생이었습니다 (was a student)
  • Ending in Vowel: 의사 + 였습니다 → 의사였습니다 (was a doctor)
• Noun + 이/가 아니었습니다(was not / were not)
  • 의사가 아니었습니다 (was not a doctor)
  • 학생이 아니었습니다 (was not a student)
