Dictionaries change. Sometimes they change for the better, but all to often the changes are only reflective of modern opinion.
New writers are often advised to write a series. The argument is you have a better marketing opportunity. If a reader likes one, he/she will likely buy the others. Is it true?
There was a time when an author only had his own imagination, his experience, and, if so blessed, a dictionary as resources. But the world has changed since those olden days.
