Causing a burning or scorching sensation; burning or parching.
From Latin 'adurens,' the present participle of 'adurere.' The suffix '-ent' marks it as an adjective describing what is burning or caustic.
Medieval physicians used this to describe caustic medicines and spices—when they said a treatment was 'adurent,' they meant it literally burned as it worked, which unfortunately was often the whole point of the cure.
