a rectangle of borrowed weightlessness you pay thousands to occasionally regret.
means A small body of still water, whether a natural pond, a puddle, or a built basin you swim in.
from From Old English 'pōl,' a word for a small body of standing water, with relatives across the West Germanic languages (Dutch 'poel,' German 'Pfuhl'). The other 'pool' — the shared kitty of money or resources — is a separate import from French 'poule,' literally 'hen,' which became gambling slang for the collective stakes (as if everyone tossed their birds into one coop); over time the two words puddled together in spelling and now share a page despite their unrelated births.
