Displacement reaction: The reaction in which the ion of a more reactive element displaces the ion of a less reactive metal by forming its own ions. Such reaction is called displacement reaction.
In short, displacement reaction is a reaction in which a more reactive element displaces the less reactive element to form its new compound.
For example: CuSO4 + Zn → ZnSO4 + Cu
In the reaction, Zn2+ ions formed from Zn atoms take the place of Cu2+ ions in copper sulphate (zinc is more reactive).
It means that Zn displaces Cu from CuSO4.
