Tatpurusa

In Sanskrit grammar a  (तत्पुरुष) compound is a dependent determinative compound, i.e. a compound XY meaning a type of Y which is related to X in a way corresponding to one of the grammatical cases of X.

There are many tatpuruṣas (one for each of the noun cases, and a few others besides); in a, one component is related to another. For example, "doghouse" is a dative compound, a house for a dog. It would be called a  (caturthī refers to the fourth case — that is, the dative). The most frequent kind is the genitive. Examples are:- The word "tatpuruşa" is an example of the type: see in the list above.
