HI, this is such an interesting topic to me. I'm developing an app to teach students vocabulary using Latin and Greek morphemes/ word parts, the suffixes teach the parts of speech. I am looking for feedback. If you would like to help, I would appreciate any feedback you have. You can find the app here - iOS Apple store Latyn Lyngo; I'm not yet selling the app, but just asking any interested people for their feedback. It is Very clunky and I haven't figured out how to motivate a learner. Perhaps the students can give me advice. You can email me at info@latynlyngo.com to tell me what you think
Thank you
