watch shows on youtube like peppa pig or kids shows. I know it sounds dumb but thats how French children learn French too, so it really does help. Also have subtitles on so you can follow and if you don't know a word look it up while you watch. It's also a fun way to learn i guess!!
Watch TV Shows and take down a few words u dont understand like the guy above said. If ur doing a monotonous task just put a french radio show in the background and even if u dont pay attention to it u will still improve.
