출입하다

The word 출입하다 is a fundamental verb in Korean that combines two characters: 출 (exit) and 입 (enter). Think of it as the complete cycle of moving through a doorway.

You will often encounter this word in formal, professional, or public settings. It is not usually used for casual movement like walking into a kitchen, but rather for accessing buildings, restricted areas, or specific sites.

When you see a sign saying 출입 금지 (No Entry), you are seeing the noun form of this word in action. It is a very practical term for navigating the world around you!

Like many Korean words, 출입하다 is rooted in Hanja (Chinese characters). The character 출 (出) means 'to go out,' and 입 (入) means 'to go in.'

Historically, these characters were used to describe the movement of people through city gates or palace entrances. Over centuries, the term evolved from describing physical travel to describing the administrative act of access control.

Because it is based on Sino-Korean roots, it carries a sense of formality that native Korean verbs often lack. It has remained remarkably stable in meaning for hundreds of years, reflecting the unchanging nature of gates and thresholds in human civilization.

You will most commonly see this word in formal signage or security documents. It is rarely used in casual conversation; for example, you wouldn't say 'I am 출입ing my house' to a friend.

Instead, use it when discussing security protocols or official access. Common collocations include 출입을 통제하다 (to control access) or 출입이 자유롭다 (to have free access).

Remember that the register is high. If you are talking to a friend, just use 들어가다 (to enter) or 나오다 (to come out) instead to sound more natural and less like a security guard.

While not an idiom in the traditional sense, the word is part of several fixed expressions:

• 출입 금지 (No Entry): The most common sign found in public spaces.
• 출입 통제 (Access Control): Used in high-security buildings.
• 출입 명부 (Entry Log): A sheet where you write your name when entering a building.
• 출입구 (Entrance/Exit): The physical door or gate used for movement.
• 자유출입 (Free Access): Used when a place is open to the public without restrictions.

The verb 출입하다 follows the standard -하다 conjugation pattern. In the present tense, it becomes 출입합니다 (formal) or 출입해요 (polite).

Pronunciation is straightforward: 'Chul' sounds like the 'chul' in 'culture,' 'ip' sounds like 'ip' in 'tip,' and 'hada' is standard. Be careful not to drop the 'p' sound at the end of 'ip' before the 'h' of 'hada'.

It is an intransitive verb, meaning it describes the act of moving rather than something acting upon an object. You don't '출입' a room; you '출입' to a room (using particles like -에).
