A spectator ion is an ion that exists in the same form on both the reactant and product sides of a reaction.
HCl(aq + NaOH(aq) = NaCl(aq) + H2O(l)
In fact, in the reaction, H+ of acid and OH- of base combine together and form water. NaCl remains as Na+ and Cl-in aqueous solution. In aqueous solution Na+ and Cl- do not undergo reaction. So these are called spectator ion.
