"On the tip of
your tongue" means that something is temporarily forgotten and almost remembered. This expression was first
used by Daniel Defoe in his book, "Moll Flanders."
An idiom is an expression or saying that
becomes part of popular culture. Idioms
often cannot be understood from the individual words that make up the expression.
