 ### Namespaced strings
 
-When an externalized string is prepended with a namespace (for example,
-`s_('OpenedNDaysAgo|Opened')`), the namespace should be removed from the final translation. For
-example, in French, `OpenedNDaysAgo|Opened` is translated to `Ouvert•e`, not
-`OpenedNDaysAgo|Ouvert•e`.
+A namespace precedes the string and is separated from it by a `|` (`namespace|string`). When you see
+a namespace before an externalized string, you should remove the namespace from the final
+translation. For example, in `OpenedNDaysAgo|Opened`, remove `OpenedNDaysAgo|`. If translating to
+French, translate `OpenedNDaysAgo|Opened` to `Ouvert•e`, not `OpenedNDaysAgo|Ouvert•e`.
