I meant just that every word means something, and there is hard to find any word meaning nothing :P

and ничто is more senseful or personificated (I am wavering about the second word though) meaning of ничего.
Ничто means something closer to the Emptiness or literally No thing - nonmaterial or zero(and is often used successfully in poetics, religion and phylosophy).

It is used in common phrases not so often as usual ничего.

And you're always welcome!
