Why Tags are needed
Without a tag an item has no meaning and maps will not show it. The tag explains to the computer what the feature actually is. If you find something where the tag has been ‘missed’, please add the tag. If an item is tagged it will have a colour, such as the red hue to the building tagged in the image above. If it’s white investigate and add the tag if it’s been missed.
The author of the project in the Tasking Manager does not know which editor the mapper will be using, so the instructions can often have a comment similar to this;
If you need to check what tag is actually on an item, click on it, then scroll to the bottom of the tagging pane and look under All Tags
Tags - a brief explanation

See the Highways section of this HOT-tips section for more information about tagging highways.
Relations - such as buildings with a courtyard or islands in a river
Some features have their tags on a Relation not on the feature itself. If you see on your screen mention of a relation, as a complete beginner the best advice is to ‘leave alone’.
For more information on relations (not a beginner subject) see;
LearnOSM - JOSM - Relations which explains relations but uses a different OSM editor, or
