Index of Tamil Noun Cases

Noun Cases in Tamil: வேற்றுமை  
In Tamil, noun cases are added to the end of a noun to indicate what in English often is a preposition "in" "on" "with" etc. General information links are provided immediately below, followed by more specific links to posts related to each Noun Case. Updated as more posts are written.

• This link to the Tamil Language Online has a brief overview of the Case suffixes.
• My post on Tamil Pronouns in each of the Noun Cases
• Howard Schiffman's article on The Tamil Case System

 The Tamil names for the cases are essentially "first case" "second case" etc. Not very descriptive! And it seems like different books have the cases in different orders, so don't memorize "second case" etc. just yet!
Nominative case - முதல்வேற்றுமை/ எழுவாய்வேற்றுமை - use the regular noun
Objective/Accusative case/Direct Object  - இரண்டாம் வேற்றுமை  - ஐ ending.  The exact rules depend on the ending vowel of the noun.
