Just published on the India page of http://www.briansteel.net is a lengthy lexical presentation of Hindi postpositions, which, for English speakers at least, are a small but important part of the difficulty of learning Hindi.
In my own study of the language over the past 5 years, I have collected about 120 simple and compound specimens. Because most bilingual dictionaries are not very generous in their treatment of postpositions, I have listed them alphabetically, with examples and translations, as a dictionary supplement. For further study and practice, there is a short Appendix of other examples of this fascinating linguistic phenomenon.
The title is:
‘108+ Hindi Postpositions. A Comprehensive List for HSL Students. Draft.’
It is available here.
