Etymology

indelible = in<not> + del<delete> + ible<capable of>

  • in (Latin prefix): Negation, meaning "not."
  • del (from Latin delere): Root meaning "to delete" or "destroy."
  • ible (Latin suffix): Adjective-forming suffix meaning "capable of."

Etymology Origin:
Derived from Latin indelibilis, combining in- (not) + delibilis (able to be deleted). The word entered English in the 16th century, originally describing ink or marks that could not be erased. Over time, it expanded metaphorically to describe lasting memories or impressions. The logic is straightforward: "not able to be deleted" → permanent.
