विभक्तिः

Sanskrit Vibhakti — The 8 Grammatical Cases

विभक्ति (vibhakti, "division") is Sanskrit's case system — the word-endings that show a noun's grammatical role in a sentence, replacing much of what English does with word order and prepositions.

Why case endings instead of word order

Because each noun's ending already signals its role, Sanskrit sentence order is remarkably flexible — "Rama eats a fruit" can be rearranged in several ways without changing its meaning, since फलं (phalam, "fruit") will carry its accusative ending regardless of where it sits in the sentence.
