It would be great if more vocabulary was gradually inlcuded..

[Buddhenath]

Unless I have missed an extra vocabulary resource, the Hindi seems to be a very narrow range of vocabulary. After a few weeks of Duolingo and previous experience of learning Hindi, I am really ready for more words in the constructions. Can anyone advise?

A language cannot be learned fluently by just using Duolingo.
Try using other resources, watching Hindi movies or television shows, making flashcards, and other things to learn more vocabulary.
