 ### Filtering enabled collectors
 
-The `node_exporter` will expose all metrics from enabled collectors by default.  This is the recommended way to collect metrics to avoid errors when comparing metrics of different familes.
+The `node_exporter` will expose all metrics from enabled collectors by default.  This is the recommended way to collect metrics to avoid errors when comparing metrics of different families.
 
 For advanced use the `node_exporter` can be passed an optional list of collectors to filter metrics. The `collect[]` parameter may be used multiple times.  In Prometheus configuration you can use this syntax under the [scrape config](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#<scrape_config>).
