ETYMOLOGIE | Freshwater, soft water, fresh-water, fresh water and sweet water are all synonyms for the same context. 1. Fresh water (with space) is the first orthography of freshwater (without space), most popular before the 20th century. It was later replaced and pushed to second most popular term by the shorter orthography, freshwater (without space) in the 1970. Today, freshwater is the most popular of all synonyms for this concept. Origin of freshwater: 2. Freshwater came from Middle English freche watur, equivalent to fresh + water. The term freshwater got into standard English usage around the 16th century. Earliest publications we could find were published after the 1550s. Some of which include:

DÉFINITION |
Naturally occurring liquid or frozen water with very low concentration in salt (less than 1,000 milligrams per litter of dissolved salts and salinity of less than 0.5), and low conductivity (conductivity often less than 200 µS/cm). It refers to all waters with low hardness including all inland aquatic systems such as streams, brooks, springs, rivers and lakes. | |||||||||||||||||||||||||||||||||

NOTES | Freshwater, also called sweet water, fresh-water, unsalted water, non-saline water, non-salty water refers to water bodies, which are renewable, and variable, but finite natural resource. Fresh water bodies are replenished through the natural water cycle, in which water from oceans, seas, lakes, forests, land, rivers and reservoirs evaporates, forms clouds, and returns inland as precipitation. Characteristics of freshwater
Examples and forms of freshwater In our everyday lives, we do interact in one way or the other with freshwater forms. Freshwater takes many forms. The gaseous form (clouds), the liquid form (e.g. rain water, well water, ponds, lakes, springs, creeks, brooks, streams, rivers) and the solid form (like icebergs, snows). Facts about freshwater Authors hold that water covers about 75% of the earth’s surface, but just a very small proportion is fresh water that can be used directly by people, animals and plants because:
Fresh water should not be mistaken for soft water, as these are two different concepts. Below is a tabular breakdown of the major differences (table 1) and similarities (table 1) between freshwater and soft water. Table 1: differences between fresh and soft water
Table 2: similarities between soft and fresh water

NOTES | The first stage is called "small male" (SM); this smallest stage has short, nearly translucent claws. If conditions allow, small males grow and metamorphose into "orange claws" (OC), which have large orange claws on their second chelipeds, which may have a length of 0.8 to 1.4 times their body size.[6] OC males later may transform into the third and final stage, the "blue claw" (BC) males. These have blue claws, and their second chelipeds may become twice as long as their bodies.[4][6] Males of M. rosenbergii have a strict hierarchy; the territorial BC males dominate the OCs, which in turn dominate the SMs. The presence of BC males inhibits the growth of SMs and delays the metamorphosis of OCs into BCs; an OC keeps growing until it is larger than the largest BC male in its neighbourhood before transforming. All three male stages are sexually active, and females that have undergone their premating moult cooperate with any male to reproduce. BC males protect the females until their shells have hardened; OCs and SMs show no such behaviour. |
