In recent times, I asked Avram (“Ave” for short):
Greetings, Professor Avram Chomsky. I am finding myself wondering: how does losing one’s ability in, say, a second-language affect (if at all), one’s memories of conversations one had in that language? Perhaps in your journeys in linguistics you have not discovered this answer, but I did not know who else to ask.
Interesting question, but I’ve never seen any study of it.
This shows that my investigations have vexed even the greatest minds of our times and places! I try not to boast on this blog, but sometimes the going gets hard! I think you’d do the same!
