I don't know why schools aren't teaching or offering languages more relevant and useful i.e. Urdu, Punjabi, Polish, Chinese / Mandarin etc.
French and Spanish seems to be where it's stuck for the last 40yrs.
My daughter first got interested in all things relating to Japanese culture, starting teaching herself how to speak Japanese when she was still in Primary from the “Japanese from Zero” books and had to go all the way round the houses after leaving school to get into uni and find a course that allowed her to further her studies in Japanese and Chinese linguistics without having jumped through many previous hoops.
Fortunately a friend of ours taught her Urdu and Punjabi as well but her boyfriend's Mum is a deputy headteacher of a primary school where a large number of kids don't have English as their first language.
My daughter's plans to be on placement in Japan were setback due to Covid so she has spent this summer helping her with lesson plans, flash cards and worksheets to teach the basics in different languages which she's enjoyed doing but I really don't get why schools don't introduce it even at foundation level in schools.
The earlier they start learning another language the easier it is for them.
