The Tai Lue language has a complex numeral classifier system in common with other Southeast Asian languages. Using data from a 344,000-word corpus of Tai Lue texts, this paper catalogues Tai Lue numeral classifiers and the constructions in which they occur. Like Standard Thai and Lao, the general inanimate classifier an⁴ and the animal classifier too¹ can substitute for specific classifiers, including classifiers for humans, when they host a demonstrative, adjective, or relative clause. Moreover, the human classifier, pʰuu³, occurs almost exclusively in these descriptive constructions.
