This is the 134th most frequent Portuguese word.
água
Water.
Água is used here literally as the liquid essential for hydration.

Água is used metaphorically here, representing the act of extinguishing or diminishing hope or enthusiasm.

The rival team dashed water on our hopes for victory.
Água again refers to the literal substance, describing its occurrence in a natural phenomenon.
