Verba volant, scripta manent
Verba volant, scripta manent is a Latin proverb. Literally translated, it means "spoken words fly away, written words remain".
This phrase seems to come from a speech of Caius Titus of the Roman Senate, who suggests that spoken words might easily be forgotten, but written documents can always be conclusive in public matters. A related meaning is that if two people want to establish a formal agreement about something, it is better to put it in writing, rather than just having an oral agreement. It could also[by whom?] to refer to the subsequent increase in recalling words that are written down than those that are merely spoken or thought about.
