Etymology

rigor = rig<stiff, harsh> + or<noun suffix>

  • rig (from Latin rigēre, meaning "to be stiff or harsh")
  • or (Latin-derived noun suffix indicating a state or condition)

Etymology Origin:
The word rigor traces back to Latin rigor (stiffness, hardness), derived from rigēre (to be stiff). It originally described physical stiffness (e.g., rigor mortis) and later expanded metaphorically to denote strictness or severity in rules, conditions, or environments. The medical sense (shivering) reflects the body's "stiff" reaction to fever.
