In case you’ve never read it, this 2014 blog post is an all time favourite of mine. It really opened up my thinking about words and definitions:
You’re probably using the wrong dictionary - http://jsomers.net/blog/dictionary
Ever since reading that, I have tended to use the 1913 Webster’s as my primary dictionary, supplemented by various modern ones where necessary. I found an acceptable iOS app for it - the UI is not good, but at least it has those shimmering definitions.
My dream would be if you could make a version of Wordnote that uses 1913 Webster’s as a dataset.
