This paper describes the development of free/open-source finite-state morphological transducers for Tuvan, a Turkic language spoken in and around the Tuvan Republic in Russia.The finite-state toolkit used for the work is the Helsinki Finite-State Toolkit (HFST), we use the lexc formalism for modelling the morphotactics and twol formalism for modelling morphophonological alternations.We present a novel description of the morphological combinatorics of pseudo-derivational morphemes in Tuvan.An evaluation is presented which shows that the transducer has a reasonable coverage-around 93%-on freely-available corpora of the languages, and high precision-over 99%-on a manually verified test set.
