To remove water from a substance or compound, making it anhydrous or water-free.
From an- (without) + hydro (water) + -ize (verb suffix meaning to make or cause). This older technical term was used in 19th-century chemistry but has largely been replaced by the more common 'dehydrate.'
Anhydrizing is the opposite of hydrating—while your body constantly hydrates (adds water), industrial processes anhydrize to create everything from drying agents to heat-generating chemical reactions.
