संस्कृतभाषा has the most advanced system of cases(7) among any language of the world, the closest second being Русский(6). The idea behind these cases is that there are only 7 types of actions that can be done with a noun, or that the noun can do. These are: प्रथमा - कर्ता - Doer द्वितीया - कर्म - Object तृतीया - करण - Instrument by which something is done चतुर्थी - सम्प्रदान - For which something is done पंचमी - अपादान - From which something emerges षष्ठी - सम्बन्ध - Related to which something is सप्तमी - अधिकरण - Inside the noun or when something goes within it अष्टमी - Greeting/Exclamation That 8th part is not that relevant, since it can be easily taken over by other words, and pronouns do not possess it, since they are never spoken to like a person. Think of any sentence in a language you are fluent in, and try to ascertain which context each noun is used in. You will always find that context within these 7 cases. The real beauty of these cases is that on changing the form of a word with respect to a particular case, its meaning becomes inherently defined into the word, and a syntax is no longer required. This is also why संस्कृतम् has the special feature of allowing any word order, yet retaining the exact meaning and intentions of the speaker. This has the added advantage of assigning a word form to a specific category of meaning, which is something easier and more intuitive to remember than memorising a mere syntactic rule. Adopting this means that syntax is now irrelevant. These inherent meanings have another effect - meaning can be conveyed without prepositions. Words like ‘with’, ‘by’, ‘for’, ‘from’ and ‘of’ are not compulsory. Let us now rewrite our original sentence: A fire burned down a man’s house. मानवस्य गृहम् अग्निः दह This sentence construction should be self explanatory for all the above points. For the sake of creating these word forms, the male विभक्ति table of संस्कृतम् shall be adopted in the singular form. For Plural forms, the same form shall be repeated.
