to say something in a way that appears to be true or real
For a woman whose criminal-law practice is only 11 months old, she sure can talk the talk. Usage notes: sometimes used in the full form talk the talk and walk the walk (to say something that appears to be real or true and show it is real or true through your actions): Most of these guys say they have religious beliefs, but only a few of them can talk the talk and walk the walk.
