We generalize several results of relatively normal nearlattices in terms of n -ideals. We introduce the notion of relative n -annihilators in a nearlattice and include some interesting results on this. Several characterizations of the set of principal n -ideals P n ( S ) are given which forms a relatively normal nearlattice in terms of relative n -annihilators. It is shown that P n ( S ) is relatively normal if and only if for any two incomparable prime n -ideals P and Q , P Ú Q =L.
