on the tip of one's tongue

Ready to say something but unable to remember it precisely. This graphic image was stated early in the eighteenth century by Daniel Defoe (Moll Flanders, 1722): “She had arguments at the tip of her tongue.” However, a similar term that is even older had quite a different meaning: at one’s tongue’s end meant that one could not keep from saying something but blurted it out. Thus, “Having always at her tongue’s end that excellent proverb” (Henry Fielding, Amelia, 1751) meant she could not stop repeating it. This version is obsolete, but “on the tip of the tongue” has been a cliché since about 1850.
