Nibbāna (Sanskrit: निर्वाण), often Nirvana. According to the Digital Dictionaries of South Asia, it probably wasn't used in the sense of "to blow out", but more likely "to extinguish" in the sense of taking away heat, fuel or air.

I’ve found some Interesting takes on the meaning of Nibbāna from a wide range of teachings.

From the Nibbāna Paṭisaṁyutta Sutta 1:

There is, bhikshus, that place where there is
no earth, no water, no fire, no wind;
no base of boundless space;
no base of boundless consciousness;
no base of nothingness;
no base of neither-perception-nor-non-perception;
neither this world nor other worlds;
with neither the moon nor the sun.
Therein, bhikshus, I say, there is
neither coming nor going nor standing;
neither dying nor arising;
neither the established nor the occurring;
nor even this sense-object.

Which is, I currently hypothesize, an awesome way for a meditator in a forest in ancient India to describe the feel of consciousness touching on its quantum superposition mechanics. For more on this, there is a good starter article in Forbes, pdf.
