 ### OpenAPI Description Structure
 
@@ -130,7 +130,7 @@ It is RECOMMENDED that the entry document of an OAD be named: `openapi.json` or
 JSON or YAML objects within an OAD are interpreted as specific Objects (such as [Operation Objects](#operation-object), [Response Objects](#response-object), [Reference Objects](#reference-object), etc.) based on their context. Depending on how references are arranged, a given JSON or YAML object can be interpreted in multiple different contexts:
 
 * The root object of the entry document is interpreted as an OpenAPI Object
-* As the Object type implied by its parent Object within the description
+* As the Object type implied by its parent Object within the OpenAPI Description
 * As a reference target, with the Object type matching the reference source's context
 
 If the same JSON/YAML object is parsed multiple times and the respective contexts require it to be parsed as _different_ Object types, the resulting behavior is _implementation defined_, and MAY be treated as an error if detected. An example would be referencing an empty Schema Object under `#/components/schemas` where a Path Item Object is expected, as an empty object is valid for both types. For maximum interoperability, it is RECOMMENDED that OpenAPI Description authors avoid such scenarios.
