PRODOME

I came across an article today discussing whether some dreams can provide early warnings of physical problems in the body. Such dreams are described as prodromal and so I thought I'd create a post centred around the use and etymology of this word. As an adjective, it derives from the word prodrome that the Online Etymology Dictionary describes as:

1640s, "a forerunner" (a sense now obsolete); by 1834 in pathology, "a prodromal symptom;" from French prodrome (16th century) and directly from Modern Latin prodromus, from Greek prodromos "a running forward, a sally, sudden attack," from pro "forward" + dromos "a running".

In fact, words built from dromos include:

• hippodrome: horse racing and chariot racing. The name is derived from the Greek words hippos and dromos. The term is used in the modern French language and some others, with the meaning of "horse racecourse". Source. In modern use, "circus performance place" (mid-19th century), and thus extended to "large theater for stage shows."
  
  
• aerodrome: a location from which aircraft flight operations take place, regardless of whether they involve air cargo, passengers, or neither. In American English, the term is airdrome. Aerodromes include small general aviation airfields, large commercial airports, and military air bases. It's use has now been largely replaced by the word "airport". Source. The word derives from the Greek aerodromos meaning "a running through the air."
  
  
• palindrome: "a word or line that reads the same backward and forward," 1620s, from Greek palindromos "a recurrence," literally "a running back." Second element is dromos "a running" and first is palin "again, back". Source.
  
  
• velodrome: a track for bicycle racing, usually with curved sides that go up steeply. Source. The term derives from "a building for bicycle races, 1892, from French vélodrome, from vélo, colloquial abbreviation of vélocipède + drome". Source.
  
  

• dromedary: "thoroughbred Arabian camel," late 13c., from Old French dromedaire and directly from Late Latin dromedarius "kind of camel", from Latin dromas (genitive dromados), from Greek dromas kamelos "running camel", from dromos "a race course". Source.

• syndrome: a group of symptoms that collectively indicate or characterise a disease, disorder, or other condition considered abnormal. Source. It's etymology is:

"a number of symptoms occurring together," 1540s, from medical Latin, from Greek syndrome "concurrence of symptoms, concourse of people," from syndromos "place where several roads meet," literally "a running together," from syn "with" + dromos "a running, course". Source.
