Water-Making Spell

"The Water-Making Spell conjures clean, drinkable water from the end of the wand."

- An excerpt from Book of Spells.

The Water-Making Spell, also known as the Aguamenti Spell is a charm that summons a jet of clear, pure water and shoots it from the tip of the caster's wand, and, depending on the caster's concentration and intentions, this charm can be anything from a simple jet of water to a wave. It is taught to sixth year students at Hogwarts School of Witchcraft and Wizardry in Charms class. The spell's incantation is Aguamenti.

Etymology
In both Spanish and Portuguese, água means "water" and mente means "mind"; these derive from the Latin terms aqua ("water") and mens ("mind"), the latter's singular dative case rendered as menti ("to the mind" or "for the mind"). Given J.K. Rowling's love of puns, it would also seem plausible that there might have been a hybrid of água and "augment", in the sense of "increase", in her mind.

Behind the scenes

 * In Harry Potter and the Deathly Hallows: Part 2, unlike in the book, Aguamenti appears as what looks like a shield of water instead of a jet. Furthermore, unlike in the book, the charm does not evaporate on contact with Fiendfyre.
