Etymology

corollary = cor<together> + ollary<to roll>

  • cor (Latin com-): "together" or "with"
  • ollary (Latin -ollarius, from volvere): "to roll" or "to gather"

Etymology Origin:
Derived from Latin corollarium ("money paid for a garland; gratuity"), originally from corolla ("small garland"). The term evolved metaphorically in logic and mathematics to denote a proposition that "rolls together" or follows naturally from a proven theorem, much like a garland complements a gift. The modern sense emphasizes logical or natural consequences.
