I am currently designing a topic index for the online grammar. The aim is to make the grammar more useful for review.
While the primary target of the grammar is students in their first year of study, the index will increase the usefulness of the grammar for people who learned Greek some time ago, but need to review in order to improve their reading skill.
The format is rather preliminary for the moment, but I have made the index live so that you can give me feedback as the work progresses. Obviously, the list of topics in the index will increase rapidly as the grammar grows. If you have suggestions for what you would like to see in the index, just let me know. I’ll do my best to accommodate.
