날씨를 확인하다.

The Korean phrase '날씨를 확인하다' (nal-ssi-reul hwag-in-ha-da) can be broken down into its constituent parts: * **날씨 (nal-ssi):** This word means 'weather'. Its etymology is somewhat debated among linguists, but a common theory suggests it comes from '날' (nal), meaning 'day', and a suffix '-씨' (ssi), which in this context might have denoted a state or condition. So, '날씨' would literally refer to the 'condition of the day' or 'day's state'. * **를 (reul):** This is an object marker particle in Korean. It indicates that '날씨' (weather) is the direct object of the verb. It doesn't carry a specific meaning on its own but serves a grammatical function. * **확인하다 (hwag-in-ha-da):** This is a verb meaning 'to confirm', 'to check', or 'to verify'. It is a compound verb formed from: * **확인 (hwag-in):** This is a Sino-Korean word (한자어, hanja-eo), meaning its roots are from Chinese characters. The characters are 確 (hwak), meaning 'certain' or 'firm', and 認 (in), meaning 'to recognize' or 'to acknowledge'. Together, they form the meaning of 'confirmation' or 'verification'. * **하다 (ha-da):** This is a very common Korean light verb meaning 'to do'. When attached to a noun (especially a Sino-Korean noun), it turns the noun into a verb. So, '확인하다' literally means 'to do confirmation' or 'to confirm'. Therefore, the phrase '날씨를 확인하다' literally translates to 'to confirm the weather' or 'to check the weather'.
