Core Grammar Rule: ~에 따르면 / 과연 ~(으)ㄹ까?
These two patterns work together perfectly to introduce a rumor and then express skepticism about it.
Meaning & Usage
~에 따르면: This pattern means "According to..." and is used to cite the source of your information. It makes your statement sound more objective, as if you're reporting something you read or heard. It's common in both written and spoken Korean, especially when discussing news, research, or rumors.
과연 ~(으)ㄹ까?: This pattern translates to "I wonder if it's really..." or "Could it really be...?" It's used to express strong doubt or skepticism about a situation. The word 과연 (indeed, really) adds a layer of deep questioning that isn't present in a simple ~(으)ㄹ까? question.
Conjugation Rules
~에 따르면: Simply attach ~에 따르면 after a noun that represents the source of information (e.g., 뉴스, 소문, 연구, 사람 이름).
과연 ~(으)ㄹ까?: This attaches to a verb or adjective stem.
Adjective/Verb stem ends in a vowel or ㄹ: Add ~ㄹ까? (e.g., 진짜이다 → 진짜일까?, 만들다 → 만들까?)
Adjective/Verb stem ends in a consonant (except ㄹ): Add ~을까? (e.g., 좋다 → 좋을까?, 먹다 → 먹을까?)
Noun + 에 따르면 / Verb/Adj + (으)ㄹ까?
Native Nuance & Mistakes
While ~에 따르면 is versatile, natives often choose different phrasing depending on the formality and the type of source.
Citing a Person vs. Citing a Text
Context: When quoting what a specific person said in a casual conversation, using ~가/이 그러는데 (someone said that...) is often more natural than ~에 따르면. ~에 따르면 is better suited for more formal or written sources like news articles, reports, or official announcements.
Example: Your friend Minji told you about a new restaurant. It's more natural to say 민지가 그러는데 저 식당 진짜 맛있대 (Minji says that restaurant is really good) than 민지에 따르면....
The Power of 과연
Context: Just using ~(으)ㄹ까? can be a simple question or a light expression of wonder. Adding 과연 in front of it injects a strong dose of skepticism and doubt. It signals that you find the information hard to believe. Use 과연 when you want to emphasize your disbelief.
