 Griptape provides [Conversation Memory](../griptape-framework/structures/conversation-memory.md) as a means of persisting conversation context across multiple Structure runs.
-If you provide it with a suitable a Driver, the memory of the previous conversation can be preserved between run of a Structure, giving it additional context for how to respond.
+If you provide it with a suitable Driver, the memory of the previous conversation can be preserved between run of a Structure, giving it additional context for how to respond.
 While we can use the [LocalConversationMemoryDriver](../griptape-framework/drivers/conversation-memory-drivers.md#localconversationmemorydriver) to store the conversation history in a local file, this may not be suitable for production use cases.
 
 In this example, we will show you how to use the [AmazonDynamoDbConversationMemoryDriver](../griptape-framework/drivers/conversation-memory-drivers.md#amazondynamodbconversationmemorydriver) to persist the memory in an [Amazon DynamoDB](https://aws.amazon.com/dynamodb/) table. Please refer to the [Amazon DynamoDB documentation](https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/getting-started-step-1.html) for information on setting up DynamoDB.
