Aberto was the incantation of a charm which unlocked doors.
Queenie Goldstein tried to use this spell to gain entry to the office of Percival Graves after a regular Unlocking Charm failed to work. However, this spell also failed, leading Queenie to speculate that Graves had locked the door with an advanced spell.
In Portuguese, aberto is the word for the adjective, "open". Interestingly, this spell and Portaberto share a similar etymology, suggesting that the two door-opening spells may be related to each other.
