Is there a verb that describes a situation where one communicate their meaning incorrectly or in a way that is difficult to understand? Something like "misconvey" or "misexpress" (I know these are not actual verbs)
miscommunicate to fail to communicate clearly, fully, or accurately; to communicate incompletely or inaccurately. (1)
It was added to the Oxford English Dictionary in June 2002 as a new word (2). It apparently originated in the early 20th century (1).
