Aquamenti :
Pronunciation:AH-gwah-MEN-tee
Description: Produces a fountain or jet of water from the wand tip.
Seen/Mentioned: Used by Fleur Delacour in 1994 to extinguish her skirt, which had caught flame during a fight against a dragon. Harry used this spell twice in 1997, both on the same night; once to attempt to provide a drink for Dumbledore, then again to help douse Hagrid's hut after it was set aflame by Thorfinn Rowle, who used the Fire-Making Spell.
Etymology: Possibly a hybrid of Latin words aqua, which means "water", and mentis, which means "mind".
Effects: 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.

Alohamora:
Pronunciation: al-LOH-ha-MOHR-ah
Description: Used to open and unlock doors; it can unseal doors upon which the Locking Spell has been cast, although it is possible to bewitch doors to resist the spell.
Seen/Mentioned: Used by Hermione Granger in 1991 to allow her and her friends to access the Third Floor Corridor at her school, which was at the time forbidden; she used it again two years later to free Sirius's cell in her teacher's prison room.
Etymology: The incantation is derived from the West African Sidiki dialect used in geomancy; it means "friendly to thieves", as stated by the author in testimony during a court case.[1]
Notes: Whilst in the first book, when the spell is cast the lock or door must be tapped once, in the fifth, a healer simply points her wand at the door to cast it, and on Pottermore the wand motion is seen as a backward 'S'.

Arresto Momentum :
Pronunciation: ah-REST-oh mo-MEN-tum
Description: Used to decrease the velocity of a moving target; it should be noted that it can be used on multiple targets, as well as on the caster himself.
Seen/Mentioned: Used by Dumbledore to save one of his students from a fall in 1993; Hermione Granger used it, to little effect, in 1998 to cushion an otherwise deadly fall.
Etymology: Likely the combination of the Anglo-French arester, meaning "to bring to a stop" and the Latin momentum, meaning "the force or strength gained whilst moving"; the literal translation hence is "Bring the force or strength gained whilst moving to a stop"
