Frequently Asked Questions
As a noun phrase meaning the water itself, it is typically written as two words: 'salt water'. The closed compound 'saltwater' is used as an attributive adjective (e.g., a saltwater fish).
In most everyday contexts, yes. However, 'seawater' is more specific to water from the sea/ocean, while 'salt water' can be any water with a high salt content (e.g., a homemade solution, water from a salt lake).
Brine is water that is fully saturated or nearly saturated with salt, often used in pickling or industrial processes. 'Salt water' is a broader, less concentrated term.
Because drinking salt water when dehydrated is dangerous—it increases the salt concentration in your blood, forcing your kidneys to work harder and ultimately worsening dehydration.
