Define a herb? Well, that was an easy enough question. A herb was just a... A herb was just... It was...

Now that she though about it, Selina had no idea how to define a herb. They had been working with herbs since Selina's very first year at school, but now that she was faced with defining what a herb was she was at a loss for words. It should have been easy. And yet, she was not a dictionary like some of her classmates always seemed to be. The redhead was coming to Hogwarts to learn. She didn't always know the answer.

So instead of raising her hand and giving a dizzying response, Selina simply say there and listened to the other answers. She knew that a herb was a type of plant, but beyond that she could not specify. Hopefully, Bentley would inform her of the correct answer. Because the sixth year did not know.
