The word doesn't translate. It is used in Spanish to designate that mysterious little area in the bullring that catches the fancy of the fighting bull when he charges in. He imagines it his sanctuary:when parked there, he supposes he cannot be hurt...
So it is, borrowing the term, that one can speak of one's "querencia"to mean that little, unspecified area in life's arena where one feels safe, serene.
