* 수 (su) meaning "water"
* 미다 (mida) meaning "to be full" or "to be complete"
Therefore, "sumida" literally means "water that is full." However, it's not used literally in Korean. It's often used as an honorific suffix, similar to "sir" or "ma'am" in English, attached to names or titles to show respect.
For example:
* 김 선생님 수미다 (Kim Seonsaengnim Sumida): Mr. Kim (honorific)
* 박 사장님 수미다 (Park Sajangnim Sumida): Mr. Park, the President (honorific)
So, while "sumida" doesn't have a direct English equivalent, it conveys respect and politeness.
