Why do you keep questioning it? (Expressing Annoyance)

This pattern is attached to a verb to express frustration or annoyance at someone's persistent and often unreasonable action or attitude. It carries a negative nuance, implying that the speaker is fed up with the repeated behavior.

Meaning & Usage

Meaning: It signifies that someone "insists on doing" or "keeps on doing" a certain negative action, much to the speaker's displeasure. It's stronger than simply stating a fact; it's a complaint.

When to use: Use it when you are criticizing someone for stubbornly repeating an action. It’s common in arguments or when pointing out a bad habit. It is most frequently combined with verbs that have a confrontational or inquisitive nature, like 따지다 (to question, to nitpick), 묻다 (to ask), 덤비다 (to charge at, to challenge), or 파고들다 (to dig into).

Conjugation Rules

Rule: This pattern is straightforward. Simply attach -고 들다 to the verb stem, regardless of whether it ends in a vowel or a consonant. The tense is expressed in the 들다 part (e.g., 들었다, 들 것이다).

Verb Stem + ~고 들다

~고 들다 is not used with all verbs. It has a strong affinity for a specific set of verbs related to arguing, questioning, and insisting. Learning these combinations is key to using the pattern naturally.

따지고 들다 (to keep questioning/nitpicking)

Context: This is the most common combination. It's used when someone is relentlessly questioning the "why" and "how" of your actions or decisions in a critical, almost argumentative way.

Example: 부장님은 제가 하는 일마다 사사건건 따지고 들어요. (My boss nitpicks every single thing I do.)

파고들다 (to keep digging into something)

Context: This implies someone is trying to investigate or inquire about something too deeply, perhaps crossing a personal boundary or being unnecessarily meticulous about a minor issue. It can mean both literally "digging into" and figuratively "prying."

따지고 들다: To keep nitpicking / 파고들다: To keep digging into / 덤벼들다: To keep challenging

The pattern ~고 들다 is not just for describing a repeated action; it's a complaint loaded with the speaker's frustration. It implies the other person is being stubborn, unreasonable, or confrontational.

~고 들다 vs. 계속/자꾸

계속 or 자꾸 simply state that an action is repeated. For example, 친구가 계속 전화해요 (My friend keeps calling) is a neutral fact.

~고 들다 adds a layer of annoyance. 자꾸 그렇게 따지고 들면 (If you keep questioning me like that) shows that the speaker is fed up with the persistent, challenging behavior.

Common Mistake

Avoid using ~고 들다 for simple, non-confrontational repeated actions. It would sound strange to say 아기가 울고 들어요 (The baby keeps crying) unless you mean the baby is crying stubbornly to annoy you. For neutral repetition, stick with 계속 울어요.

자꾸 그렇게 따지고 들면 제가 일하기가 좀 힘들어요. / 넌 왜 맨날 나중에 한다고만 하고 들어?

Since ~고 들다 is a direct expression of frustration, your response will depend on the situation and your relationship with the speaker. The dialogue shows two common ways to react.

De-escalate and Apologize (Formal)

In a professional setting, it's often best to de-escalate the situation. Acknowledge the other person's frustration, clarify that you had no ill intent, and apologize.

Follow up by agreeing to be more mindful. This shows respect for their position.

Example: 그런 의도는 아니었는데... 죄송합니다. 앞으로는 주의하겠습니다. (That wasn't my intention... I'm sorry. I'll be more careful in the future.)

Defend or Comply (Casual)

With friends or peers, you might feel the complaint is an exaggeration and defend yourself by saying they are overreacting.

Example: 알았다고. 그렇게까지 말할 필요는 없잖아. (I get it. You don't have to go that far.)

Often, this leads to reluctant compliance, as seen in the dialogue: 알았어. 지금 당장 치울게. 됐지? (Fine. I'll clean it right now. Happy now?)

그런 의도는 아니었는데... 죄송합니다. / 그렇게까지 말할 필요는 없잖아.

The feeling of ~고 들다 is inherently confrontational, so its usage depends heavily on the relationship between the speakers.

Polite Complaint (해요체)

Context: When speaking to a coworker, a senior, or someone you're not close with, you can soften the expression by using the standard polite ~요 ending. However, it still sounds quite direct and critical. It's a phrase you use when you've reached your limit and need to be firm.

Example: 제 결정에 대해 자꾸 따지고 들면 곤란합니다. (It's difficult if you keep questioning my decision.)

Casual Complaint (반말)

Context: With close friends, family, or juniors, you can use the casual 반말 form. The feeling is more direct and can sound like nagging or arguing, which is often the case in these relationships.

Polite: 왜 자꾸 아니라고만 하고 들어요? / Casual: 왜 자꾸 아니라고만 하고 들어?
