All things in life come in varying degrees of goodness. And a language must support this reality: words are required that compare and contrast different nouns/verbs and expound upon their qualities and attributes. These words are adjectives(विशेषण) / adverbs(क्रियाविशेषण). These words can be differentiated from nouns easily, since they refer to qualities rather than any idea. Ex: कुक्करः चतुरः अस् Dog is clever नर्तकः उत्कृष्ट नृत्य Dancer good dancing बालकः शनैः चालय Boy slowly walking Another modification may be made to represent their degrees, but this may also be defined using words that indicate ‘more’ or ‘most. Ex: good/better/best उत्तम/अधिक उत्तम/अधिकतम उत्तम As with plural, these words cannot be decoupled, so it makes sense to change the words themselves instead of doing this. उत्तम/श्रेष्ठम/सर्वश्रेष्ठम Returning to the sentences, they have limited functionality. There is a single doer who does something, but there is absolutely no information about the receiver of his deeds, the nature of interaction, how he/she does this or about its consequences. Say we want to say a fire burned down a man’s house: अग्निः मानवः गृहः दह अग्निः गृहः मानवः दह दह मानवः अग्निः गृहः …clearly, there is a problem. Despite adding additional words to define the interaction, we are unable to interpret it properly, since our brain interprets every word with an ः as a doer. Along with the undefined word order, attempts to assign meaning based on expected logic also fail. The third sentence will end up having meaning along ‘burn the man(‘s) fire house’, other sentences being equally nonsensical. A solution can be to define the word order - Subject Verb Object or Subject Object Verb(Syntax). Another option is to change the word forms to directly show the reader what context the noun is taking(Cases), in which case the order matters less. And of course, you may combine both these methods to make the entire ordeal simple in terms of both cases and syntax. Examples of languages that use these methods are English, संस्कृतम् and Deutsch respectively. There is no clear cut optimal answer here, since adding word forms will imply additional data per word, while a syntax is merely a rule, though it makes the language a bit restrictive. My personal preference is towards changing word forms rather than creating a syntax for learning efficiency. This choice can be supported by introducing the theory of विभक्ति(Cases) a bit rigorously.
