In Tamil, the demonstrative particles are a- (அ), i- (இ), and u- (உ) (archaic and has fallen out of use, except in Sri Lankan dialects). These demonstrative particles display deictic properties. i- (இ) is a near deixis form, which demonstrates the objects around/near the first person, while a- (அ) has distant deixis form, which demonstrates things near the 3rd person. u- (உ) was used to indicate objects near the second person, but has gradually fallen out of use. In modern Tamil i- (இ) indicates objects nearer and a- (அ) indicates objects in a distance. Using these particles demonstrative pronouns are derived. The same set of pronouns is also used as personal pronouns in 3rd person. e.g. avan (he), atu (that object/being), anta (that)
