What is a synonym for saliva?

Saliva is the term used for the clear liquid produced in the mouths of humans and many animals, primarily for the purpose of facilitating the digestion of food. The primary synonym for saliva is "spit," which is a more colloquial term that people often use to refer to saliva. Both words describe the same substance, which is secreted by the salivary glands and plays an essential role in oral hygiene, digestion, and taste.

While "goo," "fluid," and "saline" may describe various substances or liquids, they do not specifically relate to saliva. "Goo" generally refers to a thick and sticky substance, while "fluid" is a broader term that can encompass any liquid. "Saline" specifically refers to a solution of salt in water, which is not synonymous with saliva. Therefore, “spit” is the most accurate synonym for saliva, making it the best choice.
