saliva

This term refers specifically to the biological fluid produced by salivary glands. It carries a clinical or physiological connotation, often associated with the initial stages of digestion or the physical response to anticipation, such as when an animal salivates at the sight of food. As a mass noun, it is treated as uncountable. It does not have a plural form in standard usage; instead, quantities are described using partitive phrases like a drop of saliva or an amount of saliva.
