Hey,I was born monolingual and I'm currently learning my fourth language, and I have aphantasia. Aphantasia is not at all a barrier to language learning, but you will have to find your own way every now and then. There are fantastic youtube videos by Steve Kaufmann and Luca Lampariello on how to teach yourself a language. Also, the vast majority language of courses at universities and online tutors (italki.com) work great for aphantasic people.There's lot of excellent advice here https://www.summerlanguageacademy.com/blog/language-learningbut for me the keys have beenHave a good reason to learn the languageDo a little every dayHave absolute confidence that you can do this. You've learned one foreign language already and you definitely have the ability to do it againMake sure absolutely everything you study is either useful or interesting, and preferably bothGet some resources together. I use:Short stories on Lingq.comSecond hand Michel Thomas coursesThe easy languages and language pod youtube channelsDecide how you want to learn, self-study is great but the social element of a 6 month language course can be fantastic too, as can developing a friendship with an affordable one-to-one tutor. Best of luck!
