 changes might have occurred to the resources while the operator was not running.
 
 When this first reconciliation is done successfully, the next reconciliation is triggered if either
-dependent resources are changed or the primary resource `.spec` field is changed. If other fields
+managed resources are changed or the primary resource `.spec` field is changed. If other fields
 like `.metadata` are changed on the primary resource, the reconciliation could be skipped. This
 behavior is supported out of the box and reconciliation is by default not triggered if
 changes to the primary resource do not increase the `.metadata.generation` field.
