• A-hypergeometric series
• Hasse-Witt matrix

We give a short combinatorial proof of the generic invertibility of the Hasse-Witt matrix of a projective hypersurface. We also examine the relationship between the Hasse-Witt matrix and certain A-hypergeometric series, which is what motivated the proof.
