tƒŒga˜ and taŒga˜ are also used in the second person in the sense of your honour and of your honour respectively, when addressing persons worthy of high degree of reverence.

The remote demonstrative sound ƒ has given rise to the following bases, and the proximate and frontal demonstrative sounds also have produced similar ones. From them have been derived many interjections, adjectives, adverbs and pronouns.

                ƒm-ƒn-(ƒl)-(ƒ˜)
          ƒm-ƒv-ƒku. ƒl-ƒdu.

Adjectival Prefixes:

              ƒ, that; … this; e.g. ƒyidai, that place or time.

Adverbs:
            ƒn, there, in, here.
           ƒ–gu, there, …Œgu, here, ‡Œgu, in front of me.

Cf. pƒku-pƒŒgu, side.
           ƒ–du, there, …-du, here.

Cf. t†‰-t†–du, to dig.

Pronouns:- ƒn, that place, …n, this place, this world.

The liquid ‘1’ often changes into ‘t’ or ‘d’.

Naturally, all sounds produced by the most primitive people or the earliest Tamilians were long, and became shortened much later, after many generations, and that is why some demonstrative words have no shortened forms.
e.g. ƒ–du, there, …–du, here.
