Water-Making Spell

The Water-Making Spell (Aguamenti) was a charm that conjured a jet of clean, drinkable water from the tip of the caster's wand. This spell, in addition to being a charm, can also be classified as conjuration, an advanced form of Transfiguration.

History
It's unknown who invented this spell and when. The wand movement for this spell was a smooth wave movement from right to left. The Water-Making spell also appeared to be the opposite of the Fire-Making Spell, which was used to conjure flames instead.

This spell was taught at N.E.W.T.-level in Charms class at Hogwarts School of Witchcraft and Wizardry, to sixth years. It is also possible that this charm was found in the The Standard Book of Spells series by Miranda Goshawk.

Effects
Depending on the caster's concentration and intentions, this charm can be anything from a simple jet of water to a wave. It was taught to sixth-year students at Hogwarts School of Witchcraft and Wizardry in Charms class. The spell's incantation was Aguamenti.

This spell was useless against Fiendfyre, a spell that conjured cursed flames, as the water conjured from this spell will instantly evaporate on contact with the dark fire.

Etymology
In both Spanish and Portuguese, "agua"/"água" means "water" and "mente" (also in Italian) 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.
