Late Middle English: from French pétrifier, from medieval Latin petrificare, from Latin petra 'rock', from Greek.

  • The original sense of petrify was ‘to convert into stone’, from the Latin and Greek root petra ‘rock’. The sense ‘to terrify, astonish’ dates from the mid 17th century. Petroleum is from the same source—it is found in rocks. The second part is Latin oleumolive oil’ ( see oil).
