squash

[Rankin, Robert L]

The term and its sound correspondences are regular and reconstructible in Algonquian.  The sound correspondences are not regular in Siouan, the term only occurs in a small, geographically restricted group of Siouan languages.  It contains phonological sequences that are generally inadmissible within Siouan.
 
> In this light, exactly what is the reason for supposing that the 'squash' term passed from Algonquian to Siouan (or vice versa)?
