Etymology

shrewd = shrew<mischievous creature> + d<adjective suffix>

  • shrew (from Old English scrēawa, meaning "a small, aggressive mammal" or metaphorically "a spiteful person")
  • -d (a suffix forming adjectives, often indicating a quality or state)

Etymology Origin:
The word "shrewd" originally referred to the negative traits of a shrew (a small, sharp-tempered animal), implying mischief or malice. Over time, it evolved to describe sharp-wittedness and cleverness, likely because the shrew's quick, aggressive nature was metaphorically linked to mental acuity. The suffix "-d" solidified its adjectival form, transitioning from literal animal behavior to abstract human traits.
