Focus on a single context when you’re trying to grow your vocabulary in French. Our brains retain information better whenever things are placed within a context. This is why it’s much more useful to learn the vocabulary within a context and try to associate concepts together or with pictures. That’s more than just another list of words – it’s a way of efficiently circumventing a lot of unnecessary (or just unrelated) words and getting straight to the heart of a topic.
There is no shortage of topics that French learners can start with: French food, tourism in France, French work culture, French fashion, football, etc. You may choose topics that you are interested in. This will help you to master this strategy to learn French. Once you find a few topics, I recommend that you study one context at a time. And then the most important thing you can do is to directly speak and use what you just learned in French.
