For the fifth to the eighth வேற்றுமை how nouns are inflected to perform differenent functions is treated in this lesson.

The fifth differential இன் and இல் enables the inflected noun to perform four functions. They are omission, comparison.limitation and causation.

The sixth differential indicators அது and ஆது, refer to the singular and ‘அ’ to the plural of the noun concerned. ‘ஆது’ and ‘அ’ are not in contemporary use. However they occur in poems. They indicate possession either as an organic part of the noun or as an object possessed by the person concerned. ‘உடைய’ is also used as a word-part to indicate this differential.

The seventh differential has twentyeight inflexional endings from ‘கண்’ to ‘இல்’. Here subject. place. time. organ character and job (பொருள், இடம், காலம், சினை, பண்பு, தொழில்) can be applied to the noun as part of it or within its reach. This is called a place differential. (இட வேற்றுமை).

The eighth differential is vocative (விளி வேற்றுமை) in nature. To call the object indicated by the noun this differential is used. In this position the suffixes can be altered in different ways. The last letter may be altered. omitted, extended and allowed as a natural occurrence. Sometimes the permultimate letter is altered.

The call can be made from a place near or far from the action in the sentence. How nouns accept or don’t accept vocative markers is also explained in this lesson.

Same nouns are transformed when they accept the differential markers. There are other nouns which do not change.

This lesson reflects the case grammar existed in the earlier forms of English language but indicates the modern word order and the use of English prepositions.
