'to be robbed of meaning' or 'to be depleted of meaning.'

Well, Aorto, I think the worst thing that could happen to anyone, short of physical torture unto death, is to be stripped, shorn, of one's dignity, unjustly, deliberately, mercilously, callously.

So I would say the word you are looking for is "dignifile".

A stripping of another person's dignity in this manner would be a "dignifilement", as dishonorable and debased and cowardly as any physical defilement.

A "defacement" is a defilement which strips only skin deep, Aorto. It does not strip to the soul.

Likewise "desecration". It is a strike at the soul which cannot penetrate the soul.

A "dignifilement" ruptures the soul.

To recall a word from last's weeks selection of AWADs, a forceful, unjust, malacious or sadistic stripping naked of another person's dignity is a diriment of their dignity. Hence, dignidiriment. Revised 1/26.
