Etymology

Origin of syndrome

1535–45; < New Latin < Greek syndromḗ concurrence, combination, equivalent to syn- syn- + drom-, base meaning “run” ( see -drome) + -ē feminine noun suffix

Explanation

When you and your friends hang out together, you call it a party. When symptoms of an illness hang out together, they call it a syndrome. If you receive an invitation, politely decline. Syndrome comes from a Greek word that combines the root “to run” (dramein) with the prefix “together” (sun-). When many or all of the symptoms for a disease “run together,” that's a syndrome. You can also use syndrome in a figurative way to describe a type or pattern of behavior. If you have the “I'll do it tomorrow” syndrome, you put off doing a lot of things. At least you got around to reading about syndrome today.
