Off topic, but for quite a long time between the 60s and 90s it would have been unusual to have been taught much about English grammar in an English state school - the focus was much more on creative and expressive writing. I believe it’s different now and children are taught about grammar, but you have an awful lot of people in their 30s and 40s who know almost nothing about grammar beyond the basics (‘a noun is a name, adjectives are ‘describing’ words’). I have long said that this is one of the reasons that we English people are so bad at learning foreign languages - we don’t actually learn our own well! If you’ve never been taught about grammar or if you’ve never had the opportunity to learn Latin, for example, which isn’t like learning a language but is more like a really intensive course in grammar, you are going to be pretty screwed when it comes to learning many other languages. My secondary school taught German and it’s practically impossible to learn that language properly without having an understanding of grammar - I studiedit for five years, I spoke it with a reasonably good accent and got a good GCSE but can I have a conversation beyond parroting phrase-book sentences? Nope …
