Hindi/Urdu (HU) numbers 10–99 are highly irregular, unlikethe transparent systems of most languages. I investigate themorphological decomposability of HU numbers using a seriesof computational models. While these models classify mostforms accurately, problems are encountered in high-frequencyforms of low cardinality, suggesting that some HU numbers aremore transparent (i.e., morphologically decomposable) thanothers. These results are compatible with a dual-route accessmodel proposed for the processing of numeral forms.
