Building (noun) – el edificio
(Pronounced eh-dee-fee-thee-oh)
To remember that building is pronounced eh-dee-fee-thee-oh (edificio) in European Spanish, use the following mnemonic:
Their building was completely edible, and they each feasted until the only (edificio) thing left was the front door.
Edificio is masculine, so it's el edificio. Imagine an elephant that looks like a building.
