Interesting point about Hindi not having a word for 'DIVORCE'. But as tinker pointed out, there are many more languages than 'hindi' for 'hindus'. (Lets hope the spellings dont mislead people :-p) . In fact, from a strictly theological point of view it is Sanskrit thts the language in which the texts have been written not Hindi.

Which lead me to look for words for Divorce in Sanskrit and this is what I found. Should say this is new to me too, but the words sound oddly familiar.

1. Divorce: Parityagah ( N ); Vivahavichhedah ( N )
Vivahalopah ( N )
(Pari+Tyaj ( v.t. 1 PP )
Vivaham Lopaya ( causal or Prayojak of Lup, 10 PP ))

2. Divorcee (Male & Female called)
*** Parityaktah ( N, M ); Parityakta ( N F )

3. Re-marriage of the divorcee.
*** Punar+Bhoo ( 1 PP ) >>>>>>>>Punarbhooh ( N F & M )
Punar+Vaha ( 1PP )>>>>>>>>>Punaroodah ( N M ), Punaroodha ( N)

A search for the etymology of 'Divorce'tells me that the word has its origins around 14th century. Wonder what it was called before that!

(late 14c., from O.Fr. divorce (14c.), from L. divortium "separation, dissolution of marriage," from divertere "to separate, leave one's husband, turn aside" (see divert). Not distinguished in English from legal separation until mid-19c. The verb is late 14c., from O.Fr. divorcer)
