Because of my very late language acquisition (English as primary language), I have tried to learn just the bare basic things, like characters, consonants, vowels, pronunciation, and few basic words. I know words, but can't speak fluently in español, have tried to learn Hindi, and was taught one phrase in Arabic (I learned it as "good night" nearly 25 years ago and haven't forgotten it). I know some sign. I created my own alphabet and ways to write and pronounce the letters.
I struggle hard to learn a second language. I didn't speak English fluently until I was just past eight years old. Verb conjugations in español trip me up because I don't use it often enough to remember how to conjugate. The only time I run into people who speak Hindi is at my store. About the best I do is imitate words very closely to that of some native speakers, depending on the language because of my speech therapy experience. I can do the accent in español better than most people who are hearing English speakers.
