Excessive or incoherent talkativeness; a synonym for verbosity. In psychology logorrhea represents a communication disorder of incoherent speech.
Dated back to 1878, this word stems from the Greek logos, representing a word, and the Greek suffix of ‘rrhoea’ coined by Hippocrates and representing anything that is flowing through something else. And yes, the resemblance to diarrhea is not accidental, both came about from the same flowing origin.
Why this word?
Because the British use the phrase verbal diarrhea, a phrase that is also found in the Urban English Dictionary with quite a few meanings to it, mostly representing a person who speaks his mind without any filters, consequences of which could be profoundly funny or insulting, to the one listener.
Another definition is of ‘a condition suffered by an individual who has the inability to shut the f*** up’.
