The final thing I did while learning Hindi (and still do!) is I keep a small notebook with me. The front half of the book is dedicated to grammar notes from YouTube or book lessons.
The second half is a glossary where I write any new words I’ve acquired during the day. By doing this, I’ve created my own Hindi grammar reference book and vocabulary builder where I can go back and test myself on new words.
But more importantly, when you write grammar lessons and words down, it helps you remember them better than just listening or reading.
One other vocabulary notebook I use is in the Google Translate app on my mobile phone. With it, you can look up words and then star them so they show up in your Phrasebook for later review.
These days I’m using an iPad Pro, Apple Pencil, and GoodNotes for all my note-taking and writing practice.
