Hermione Granger, Ron Weasley, and Harry Potter used this spell frequently through out the 1997-1998 school year to set up a tent for themselves while hunting Lord Voldemort's Horcruxes during the height of the Second Wizarding War.

Erectum is past participle of erigere, a Latin verb meaning "to erect".
