2. Time Indicating Nouns
Just like any other lanuages, there are nouns that indicate time in Korean, such as 오전(morning), 오후(afternoon), 저녁(evening), 아침(morning), 점심(lunch), 저녁(dinner), days of the week, various holidays, and more. Both ‘-에’ and ‘-때’ can be used after these nouns, but in terms of naturalness, ‘-에’ tends to sound more fluent. Therefore, if a question appears in a test like TOPIK, choosing ‘-에’ would be appropriate. However, in actual usage, ‘-때’ is also commonly used.
- 오전 때 (Δ) / 오전에 (O)
- 저녁 때 (Δ) / 저녁에 (O)
- 수요일 때 (Δ) / 수요일에 (O)
- 주말 때 (Δ) / 주말에 (O)
- 방학 때 (Δ) / 방학에 (O)
3. N 때 vs N에
Even though there may not be a significant difference in usage between -때 and -에, when attached after consecutive dates like 추석 (Korean Thanksgiving) or Christmas, the nuance between the two changes. That is, the form N에 indicates the specific day(s) of the holiday, whereas N 때 refers to the approximate time period encompassing just before, during, and after the holiday. For example, 추석에 refers to the 추석 day, while 추석 때 may imply the span of the few days surrounding the holidays including the day before and the day after 추석.
