desiccate

This one has the feel of a word cooked down in a laboratory flask. Latin had siccus for “dry,” and then slapped on de- in the sense of “thoroughly” or “away,” producing a form that meant not just dry, but dried to the bone — the verbal equivalent of wringing out a towel one more time for good measure. Medieval medicine was already fond of it: a 15th-century translation of Chauliac uses desiccate as a learned, bookish adjective before English promotes it to full verb status in the 1570s. That same dry little Latin family keeps turning up elsewhere: desiccant packets in shoe boxes, desiccation in geology, and even the emotional sense of someone who feels emotionally drained after one too many political debates. It’s a word that doesn’t merely remove water; it leaves you hearing the hiss of evaporation.
