+#### Use `count` Instead of Pluralization
+
+If the value being recorded represents the count of concepts signified
+by the namespace then the metric should be named `count` (within its namespace).
+The pluralization rule does not apply in this case.
+
+For example if we have a namespace `system.processes` which contains all metrics related
+to the processes then to represent the count of the processes we can have a metric named
+`system.processes.count`. The suffix `count` here indicates that it is the count of
+`system.processes`.

 The following semantic conventions aim to keep naming consistent. They
