Just as "illakanam", the Tamil word for grammar, is derived from the Sanskrit "laksana", so too a number of other words that have to do with grammar in that language are of Sanskrit origin. For instance, there are two terms used in Tamil grammar, pakuti (pahuti) and vikuti (vihuti). To illustrate in the word "Ramanukku" (for Raman ), "Raman " is pakuti and "ku" is "vikuti". Both terms pakuti and vikuti are derived from Sanskrit grammar. "How do you say so? " it might be asked. "Is it not pakuti an original tamil word derived from "pakuttal? "
Pakuti in the sense of that which has been divided is indeed a Tamil word. But I say that there is another pakuti that is a corrupt form of the Sanskrit "prakarti". It is in the sense of "prakarti" that the word "Raman" in "Ramanukku" is described as pakuti. As for "vikuti" it is from the Sanskrit "vikriti": there is no such word as "vikuttal" in Tamil corresponding to pakuttal. From the undisputed fact that vikuti is from vikriti, we may conclude for certain that pakuti is from prakrti.
(Vikrti also called "pratyaya", that which gives many meanings to the same prakrti. When it is said "Ramanai aditten"-(I) beat Raman-the pratyaya "ai" added makes Raman the person who is beaten. If it is said Ramanal adipatten-(I) was beaten by Raman-the prakrti Raman with the al makes him the one who beat. )
It is not my purpose to claim that Sanskrit is superior to Tamil. When do feelings of superiority arise to make us happy? When we are conscious of differences between what we believe is "ours" and what we believe is "theirs". Where we to have racial bias, we could be tempted to speak in appreciative terms of what is "ours" and to deprecate what is "theirs". If we realise that to harbour feelings based on racial differences is itself wrong, that our languages have sprung from the same family, from the same cultural tradition, there will be no cause for speaking highly of one language at the expense of another.
On the subject of grammar I have mentioned certain facts and it is not my intention to elevate one language above another.
