들여오다

Both mean 'to bring,' but 들여오다 specifically implies bringing something into a place, often from outside. 가져오다 is a more general 'to bring' without that specific direction or 'into' nuance. Think of 들여오다 as 'to bring in' and 가져오다 as just 'to bring.'

While it technically *could* be used for people in a very formal or transactional sense (like 'to bring in new employees'), it's much more common and natural to use 다른 verbs like '데려오다' (to bring a person) for people. 들여오다 is primarily for objects or concepts.

들여오다 is a fairly neutral verb. It can be used in both formal and informal contexts. The formality often depends more on the particles and sentence structure around it than the verb itself.

수입하다 specifically means 'to import' in a commercial or economic sense (e.g., importing goods from another country). 들여오다 is broader and can be used for bringing in anything, not just commercially imported items. You can 들여오다 furniture into your house, but you wouldn't typically 수입하다 it in that context.

Yes, you absolutely can! For example, you can '문화를 들여오다' (to bring in culture) or '새로운 기술을 들여오다' (to bring in new technology). It's great for talking about introducing new things or ideas into a system or society.

The past tense of 들여오다 is 들여왔어요 (informal polite) or 들여왔습니다 (formal polite). The base form '오다' becomes '왔다' in the past tense.

The future tense is typically formed by adding -(으)ㄹ 거예요 or -(으)ㄹ 겁니다. So, you would say 들여올 거예요 (informal polite) or 들여올 겁니다 (formal polite).

네, 여기 있어요: '새로운 가구를 들여왔어요.' (I brought in new furniture.)

Yes, it can be used passively, often with the construction '들어오다' or by using a passive auxiliary verb. For example, '새로운 기술이 들여와졌어요' (New technology was brought in), though '들어오다' is more common for 'to come in' passively.

A common mistake is using it interchangeably with 가져오다 when the 'bringing into' nuance isn't present, or trying to use it for people too often. Remember its specific meaning of bringing something *into* a place or system.
