Oriya classifiers are distinguished into two types: the -Taa type, which is generated higher than the numerals in the phrase structure tree, and the other type which is generated lower than the numerals.
One characteristic of the Oriya number system is that number is realized either as a numeral or as nominal inflection but not as both, i.e, the plural marker and a number word cannot co-occur.
Besides the definite article -ka, Oriya has a null definite article which has all the properties of -ka. These two forms have two features: a number feature which can trigger classifier-raising (through head-to-head movement of the classifier) and a definiteness feature which can trigger NP-raising (through SPEC-to-SPEC movement of the NP).
A demonstrative and an article can co-occur in Oriya; hence it is proposed that the Demonstrative (Deix) projects to DeixP, which is generated immediately above DP.
