 # Prefer putting braces around variable references even when not strictly required.
 
 This error is optional and not enabled by default.
+
+## Problematic code:
+
+```shell
+partial_path='example'
+
+curl "http://example.com/$partial_path_version/explain.html"
+```
+
+## Correct code:
+
+```shell
+partial_path='example'
+
+curl "http://example.com/${partial_path}_version/explain.html"
+```
+
+## Rationale:
+
+If a variable gets called, and there is a string that gets appended to the variable that could get misinterpreted as possibly part of the name of the variable. Then it will not call the right variable.
