Serosity
/sɪˈrɒs.ɪ.ti/noun
The quality or state of being serous; a thin, watery discharge or fluid.
Did you know?Serosity is built on Latin *serum*, meaning “whey” or “watery fluid,” a root that also gave us *serum* and *serous*—terms tied to the body’s separated liquids, not magic, but very much the language of hidden fluids.
