설명해주다

The word 설명해주다 is a compound verb that is essential for daily communication in Korean. It is formed by the noun 설명 (explanation) and the auxiliary verb 해주다 (to do for someone).

Using this word shows that you are not just explaining, but you are doing it for someone else. It carries a nuance of helpfulness and care. Whether you are teaching a friend how to use an app or clarifying a complex rule, this word is your go-to choice.

The root 설명 (說明) comes from Hanja, or Chinese characters. '설' (說) means to speak or persuade, and '명' (明) means bright or clear. Together, they mean to make something 'speak clearly' or 'brighten up' with words.

The addition of 해주다 is a purely Korean grammatical construction. It evolved as the language became more focused on social hierarchy and the 'giving' or 'receiving' of actions, reflecting the collectivist nature of Korean culture where helping others understand is a social virtue.

You use 설명해주다 when you want to emphasize that you are helping someone. It is much warmer than just saying '설명하다'.

Common collocations include 자세히 설명해주다 (explain in detail) or 쉽게 설명해주다 (explain easily). It is used in almost all registers, from casual conversations with friends to polite requests in a professional setting.

While not an idiom itself, it is often paired with: 1. 귀에 못이 박히도록 설명해주다 (to explain until someone is sick of hearing it). 2. 입이 아프게 설명해주다 (to explain until one's mouth hurts). 3. 하나부터 열까지 설명해주다 (to explain everything from A to Z). 4. 눈높이에 맞춰 설명해주다 (to explain at someone's level). 5. 친절하게 설명해주다 (to explain kindly).

Grammatically, it follows the standard verb conjugation rules. In the past tense, it becomes 설명해줬다. It is a transitive verb that usually takes the object particle -을/를.

Pronunciation-wise, be careful with the 'ㄹㅁ' cluster in '설명'. It is often pronounced as '설명' [설명] with a clear 'l' sound followed by 'm'. Practice the transition from the nasal 'm' to the 'h' sound in '해주다'.
