Oriya language
Sutton devoted himself to learning the local Odia language, as soon as he arrived the mission station. Sutton being a gifted translator, soon compiled an Odia grammar, and dictionary in three volumes, as well as translating a number of English books such as Pilgrim's Progress by John Bunyan – in Odia named "Swaga Jatrira Britanta" – and also a complete translation of the Bible. Amos Sutton's "Introductory Grammar of Oriya language" published in 1831, happens to be the oldest publication available in the Oriya Language Collection to date.
