Nouns

Nouns and pronouns are inflected for case, including nominative, objective, genitive (possessive), and locative. The case marking pattern for each noun being inflected depends on the noun's degree of animacy. When a definite article such as -টা -ṭa (singular) or -গুলো -gulo (plural) is added, as in the tables below, nouns are also inflected for number.

In most of Bengali grammar books, cases are divided into 6 categories and an additional possessive case (the possessive form is not recognised as a type of case by Bengali grammarians). But in terms of usage, cases are generally grouped into only 4 categories.

When counted, nouns take one of a small set of measure words. Nouns in Bengali cannot be counted by adding the numeral directly adjacent to the noun. An appropriate measure word (MW), a classifier, must be used between the numeral and the noun (most languages of the Mainland Southeast Asia linguistic area are similar in this respect). Most nouns take the generic measure word -টা -ṭa, though other measure words indicate semantic classes (e.g. -জন -jôn for humans). There is also the classifier -khana, and its diminutive form -khani, which attaches only to nouns denoting something flat, long, square, or thin. These are the least common of the classifiers.

Measuring nouns in Bengali without their corresponding measure words (e.g. আট বিড়াল aṭ biṛal instead of আট টা বিড়াল aṭ- ṭa biṛal "eight cats") would typically be considered ungrammatical. However, when the semantic class of the noun is understood from the measure word, the noun is often omitted and only the measure word is used, e.g. শুধু এক জন থাকবে। Shudhu êk- jôn thakbe. (lit. "Only one- MW will remain.") would be understood to mean "Only one person will remain.", given the semantic class implicit in -জন -jôn.

In this sense, all nouns in Bengali, unlike most other Indo-European languages, are similar to mass nouns.
