I've found a promising online language learning app. Duolingo. My wife's learning Italian by using it. I have started to use it for German improvement. I could use my wife, she's a German teacher but I suspect that tension would arise so an alternative avenue was sought and found...
I'm confident that I'll cope. Much to my wife's chagrin I demonstrated the ability to read and understand Greek when we holidayed in the Greek Islands. Being a scientist/engineer, the Greek alphabet and phonetics were second nature. and I quickly mastered basic transactional Greek.
