This is perfect for all Biblical Greek scholars and students. It includes all the Koine Greek diagrams you will ever need to help you with parsing.

If you want to see the whole diagram, just pinch it down to fit! You can also switch to landscape mode by rotating it sideways while in the List View window.

These are the diagrams my Greek professor made me learn. They are identical to the diagrams you would find in "Basics of Biblical Greek" by William D. Mounce.
