To delete a topic, you need to locate it first. To locate a topic point it in topic table or a topic tree. Or open it in topic panel. Topic in a table or a tree is deleted using context options Delete topic or Topics > Delete topics. Topic table allows also deletion of multiple topics at once.
Topic deletion is always confirmed from the user. Topic deletion removes also all associations where the deleted topic plays a role.
Topic can't be deleted if it is an association role, an association type or an occurrence type. To delete such a topic, you first need to delete associations and occurrences the topic defines.
Note that topic merge may look like a topic deletion as all properties of the topic are added to another topic.
