The word "confabulate" has an unusual range of meanings. In everyday English, it can simply mean to talk or converse, often in a relaxed way. In psychology and medicine, however, the same word is used for a very different phenomenon: producing false or inaccurate information without deliberately trying to deceive someone. The contrast makes "confabulate" an especially interesting word to understand in context.
Pronounced "kuhn-FAB-yuh-layt", the verb is most often associated with conversation or with accounts that contain invented details. Its meaning depends heavily on how it is being used and the subject being discussed.
