 There are eight such "vibhaktī" (विभक्ति) in Marathi.The form of the original word changes when such a suffix is to be attached to the word, and the new, modified root is referred to as "saamaanya ruup" of the original word.For example, the word "ghodā" (घोडा “horse”) gets transformed into "ghodyā-" (घोड्या-) when the suffix "-var" (वर- “on”) is attached to it to form "ghodyāvar" (घोड्यावर “on the horse”).
