Explanation:
* First Declension: This is the "A" stem declension, and it's the most common way to decline masculine nouns ending in "i".
* Second Declension: This is the "I" stem declension. It's less common, but it can be used for certain masculine nouns.
* Nominative: The subject of the sentence (e.g., "Rishi is wise").
* Accusative: The object of the verb (e.g., "I saw the Rishi").
* Instrumental: Used to indicate the means (e.g., "He wrote with a Rishi's pen").
* Dative: Indicates the indirect object (e.g., "He gave the book to the Rishi").
* Ablative: Indicates separation (e.g., "He came from the Rishi's house").
* Genitive: Shows possession (e.g., "The Rishi's wisdom").
* Locative: Indicates location (e.g., "He is in the Rishi's presence").
* Vocative: Used for direct address (e.g., "O Rishi, listen to me").
Note:
* The first declension is generally considered the more common and natural way to decline "Rishi".
* The vocative form in both declensions is the same as the nominative form.
