nước ngọt
/ˈfreʃwɔːtə(r)//ˈfreʃwɔːtər/The term "freshwater" is a relatively straightforward combination of the words "fresh" and "water". It originated from the need to distinguish between water that is drinkable and suitable for life, and saltwater found in oceans and seas. "Fresh" refers to the absence of salt and other impurities, while "water" simply denotes the liquid substance itself. The term likely emerged in the late Middle Ages, as humans became increasingly aware of the differences between water sources.
