Hello Ali. I have used mind mapping, but to study zoology and botany.  It works with English vocabulary too and I think it is a good idea to learn new words around a theme.

I was not familiar with this concept, so I had to look it up. I don’t know if it’s the same thing you’re referring to, but lately I decided to make some lists of vocabulary related to a main subject. For example, talking about holidays and writing down all the useful words related to it. I think it could help to remember the vocabulary.

I haven't heard of it, so I looked it up. 😁 I actually think it's quite useful! I think I may start creating mind maps for Japanese and Spanish. (I'll need to see more examples to get a better feel of how to do one properly,) but I really think it's helpful in sorting out terms, vocabulary or even phrases you've learned in a language. 😄

Thank you all
