| In our research paper, we examine compounding and suffixation as productive means of word formation in the language of Orhon inscriptions. |
| The use of pseudowords in addition to real words allowed us to assess suffixation without support of lexical knowledge. |
| The perfective aspect is usually formed from the imperfective either by prefixation or by suffixation. |
| Languages in the region display an usually high prevalence of suffixation patterns used to signal syntactic subordination. |
| This basic aspect, however, could be reversed by morphological devices such as ablaut, suffixation, and reduplication. |
| Note also that while there is limited suffixation for TAM, most of the morphology on verbs is prefixal. |
