 "In topology, the '''closure''' of a subset $S$ of points in a [[위상공간,topological_space|topological space]] consists of
  all points^^WpEn:Topology_glossary#P^^ in $S$ together with
  all limit points^^WpEn:Limit_points ....[[극한점,limit_point]]^^ of $S.$

 The '''closure''' of $S$ may equivalently be defined as the union^^[[WpEn:Union_(set_theory)]]^^ of
  $S$ and
  its boundary^^[[WpEn:Boundary_(topology)]]^^,
 and also as
 the intersection^^[[WpEn:Intersection_(set_theory)]]^^ of all [[닫힌집합,closed_set|closed sets]] containing $S.$

 Intuitively, the '''closure''' can be thought of as all the points that are either in $S$ or "very near" S.
 A point which is in the '''closure''' of $S$ is a point of closure^^[[WpEn:Adherent_point]]^^ of $S.$ // WtEn:adherent_point Ndict:adherent+point Ggl:adherent+point ...

 The notion of '''closure''' is in many ways dual^^[[WpEn:Duality_(mathematics)]]... [[쌍대,dual]] [[쌍대성,duality]]^^ to the notion of interior^^[[WpEn:Interior_(topology)]]^^.
