Fun Fact
The word “jettison” has nautical origins, dating back to the early 15th century. It comes from the Anglo-French “jetteson,” derived from Latin “jactare” meaning “to throw.” Originally, it referred specifically to the act of throwing goods overboard to lighten a ship’s load during a storm or other perilous situations. This practice was so common that it led to the development of maritime laws regarding the recovery of jettisoned goods. Over time, the word’s usage expanded beyond maritime contexts, becoming a metaphor for discarding any burden or unnecessary element. Its evolution from a specific nautical term to a broader concept demonstrates how language adapts and extends meanings across different domains.

Caustic comes from the Latin causticus, derived from the Greek kaustikos — from kaiein, meaning “to burn.” It entered English in the late 14th century first in its literal chemical sense, describing substances that burn or corrode on contact, before its meaning extended to describe the burning quality of sharp, cutting speech.
