What does desiccating mean?
Desiccating is the present participle of the verb desiccate, meaning to remove moisture from something completely, and it also functions as an adjective describing anything that has a thorough drying effect. In literal use it appears most often in scientific and environmental contexts — desiccating winds, desiccating heat, or desiccating agents such as silica gel that draw water out of materials. Figuratively, the word carries a vivid, somewhat literary force: a desiccating bureaucracy or a desiccating routine is one that drains energy and vitality just as hot wind drains moisture from soil. The word derives from Latin siccare, 'to dry,' via desiccare, and its relatives include desiccation and desiccator. Formal in tone, desiccating suits precise, descriptive prose where ordinary words like 'dry' would feel too weak.

From Latin 'siccare', to dry — the same root that gave us the word 'siccative', the term painters use for pigments that speed drying.

Etymology of desiccating
Desiccating comes from the Latin verb desiccare, formed from de- ('thoroughly') plus siccare ('to dry'), itself rooted in siccus, 'dry.' The English verb desiccate entered the language in the late sixteenth or early seventeenth century, likely through scholarly or scientific Latin usage. Its cognates within English are largely learned derivatives sharing the same root, including desiccation, desiccative, and desiccator.

Usage notes
Formal to technical in register; common in scientific, agricultural, and meteorological writing. The figurative sense, describing anything that withers enthusiasm or vitality, is literary rather than conversational.
Don't confuse with
Both mean removing water, but 'desiccating' suggests thorough drying by air, heat, or absorbents and often a technical register, while 'dehydrating' is the more common everyday term for losing body fluids or preserving food.
