Les, as I understand anona, she was able to make up examples, in fact she did, but then decided it would be more useful to give an example that had already been published, which I tend to agree with.
A risk in making up examples is that you might come up with something that nobody would ever really say. Once somebody queried why assort is a rare word. It would be easy enough to come up with an "every day" usage example: "She decided to assort some biscuits [or cookies if you prefer] onto a plate." But nobody actually uses assort like that. When I checked in a collection of published text, I found 254 cases of assorted, but only one of assort, and that was in a scientific publication. Hence assort remains rare.
When I did a quick check in the newspaper here in Melbourne, the Age, I found lots of examples of nuanced, including two from today alone, so there could be a strong case for making it common, but I'll look into it more fully some other time.
