<human>:  What is the origin of the word ‘complication’?
<bot>: The word “complication” comes from the Latin word “complicatio” which means a tangle. The word “complication” was first used in the medical field in the late 1500s to describe a group of symptoms that occur together. For example, if a patient has a fever, a cough, and a headache, these symptoms are all considered to be complications of the same disease.
