Although this website, all of the wordlists as well as all of the other online resources on this website are and always will be free, the cost of running the various websites and URLS, as well as the cost of creating and updating our many free apps, definitions etc. has quickly added up over the years. We have done all of this work for the benefit of learners, teachers, researchers and materials developers without grants or funding of any kind, paying all costs on our own.
If you or your institution have benefited from our work and you feel led to make a small contribution, it would be most appreciated and will certainly help hasten the development of more lists and tools in the future.
We have not yet set up an official account for this
