The process or quality of gradually melting or dissolving by absorbing moisture from the air.
From 'deliquesce' plus the suffix '-ence,' which creates a noun describing a state or quality. The '-ence' suffix is the standard way to convert verbs (especially those with '-esce') into nouns.
Deliquescence is used in chemistry labs and by scientists studying climate—some substances are so hygroscopic (moisture-loving) that they'll spontaneously turn to liquid if the humidity is high enough!
