Indic Loanwords in Spoken Thai: William J. Gedney, 1947
The acknowledged father of modern Tai linguistics, Gedney's PhD thesis
was the first formal, large-scale study of Pali and Sanskrit loans in modern Thai.
Gedney's thesis differed from contemporary Thai analyses by ignoring
orthography, and instead focusing on predictable, regular, phonemic change.
A half-century later, Gedney still provids an
unequalled picture of Thai's historical development.
