shrewdness

the word 'shrewdness' originates from the middle english adjective 'shrewed', which initially meant 'wicked, evil, or dangerous'. this term was derived from 'shrew', a small mammal once believed to be venomous and metaphorically applied to a malicious or scolding person. over centuries, the negative connotation of cunning evolved into the positive sense of sharp-witted intelligence and keen practical judgment. the suffix '-ness', of old english/germanic origin, was added to form the abstract noun denoting the quality of being shrewd, completing the transition from a trait of malice to one of astute discernment.
