I'm currently in the midst of a 5-session on-line SWI course. The context for what we study is very much driven by the questions participants ask. After the first session of the current Nov-Dec 2019 course, a participant asked a great question about one of the activities that gets to central concepts that anyone studying orthogaphy needs to attend to. I have taken the text of that question and my response to create the document that you can download HERE. By sharing this document here, I hope to help others working with orthography who don't happen to be in our course right now.
If you download the pdf, you will find links to many other resources.
The image below is just a screen shot. You need to download the document to read the whole thing and to get access to the links!
