 == Nodes, ways, and relations == #NodesWaysRelations
+
+=== Tags ===
+
+Tags provide meaning to the objects. Without them, any other object would be useless and meaningless. Each of three other types can have group of tags.
+
+Simplests example is [osmwiki:Key:drinking_water drinking_water=yes] it is present globally.
+
 === Nodes ===
-[[Image(source:trunk/images/data/node.png,20,bottom,margin-right=15,nolink)]] A **node** is an individual point with a defined position. 
+[[Image(source:trunk/images/data/node.png,20,bottom,margin-right=15,nolink)]] A **node** is an individual point with a defined position. ''With respective tags'' it can be used to indicate shops, benches, individual trees or points of drinking water.
 
 === Ways ===
-[[Image(source:trunk/images/data/way.png,20,middle,margin-right=15,margin-bottom=5,nolink)]] A **way** is a sequence of nodes. Despite its name a way doesn't represent ways in the real-world only. An OSM **way** is also used to represent a river, the boundaries of a country, or even a building.
+[[Image(source:trunk/images/data/way.png,20,middle,margin-right=15,margin-bottom=5,nolink)]] A **way** is a sequence of nodes. OSM **way** used to represent linear objects, ''with respective tags'' it can used to describe: a river bank, tree row, kerbs in the streets (among other uses).
 
-==== Areas or Closed Ways ==== #ClosedWays
-[[Image(source:trunk/images/data/closedway.png,20,middle,margin-right=15,margin-bottom=5,nolink)]] If a **way** is closed, i.e. if the last node is the same as  the first node, it is also called an **area**. 
+==== Areas ==== #ClosedWays
+[[Image(source:trunk/images/data/closedway.png,20,middle,margin-right=15,margin-bottom=5,nolink)]] If a **way** is closed, i.e. if the last node is the same as  the first node, it is also called an **area**. Old term for this is ''Closed Ways'' (it is still present at wiki, used in software and by some mappers; other part uses "geometry" when talking just about shape of the objects, without tags).
 
-Sometimes single closed way is not enough to represent an object and then you use a [wiki:Help/Concepts/Object#typemultipolygon multi-polygon] 
+Sometimes single area is not enough to represent an object (for example, a lake with an island in it), then you have to use a [wiki:Help/Concepts/Object#typemultipolygon multi-polygon]
