다시 한번 설명해 주시겠어요?

The phrase is a combination of native Korean words and a Sino-Korean verb. * **다시 (da-si)**: This is a native Korean adverb meaning 'again' or 'once more'. Its origin is ancient and deeply rooted in the Korean language, without a direct traceable foreign etymology. * **한번 (han-beon)**: This is composed of '한 (han)', meaning 'one' (native Korean numeral), and '번 (beon)', a native Korean counter for 'times' or 'occasions'. It literally means 'one time'. * **설명하다 (seol-myeong-ha-da)**: This is a Sino-Korean verb meaning 'to explain'. It is derived from Chinese characters: * **說 (설, seol)**: meaning 'to speak, to say, to explain'. * **明 (명, myeong)**: meaning 'bright, clear, to understand'. So, '설명하다' literally means 'to speak clearly' or 'to make clear'. * **-해 주시겠어요? (-hae ju-si-ge-sseo-yo?)**: This is a complex grammatical construction that adds politeness and a request. * **-해 주다 (-hae ju-da)**: This is an auxiliary verb construction meaning 'to do (something) for someone'. '주다 (ju-da)' means 'to give', but when attached to a verb stem, it indicates performing an action for the benefit of another. * **-시- (-si-)**: This is an honorific suffix, showing respect to the person being spoken to. * **-겠- (-get-)**: This is a volitional/presumptive suffix, often used in questions to ask about the listener's intention or possibility, making it a polite request. * **-어요 (-eo-yo)**: This is a polite ending for declarative sentences and questions in informal polite speech. In summary, the phrase '다시 한번 설명해 주시겠어요?' is a well-established and essential part of modern Korean communication, blending native Korean elements with Sino-Korean vocabulary to form a polite and clear request.
