House – la casa
(Pronounced ka-sa)
To remember that house is pronounced ka-sa (casa) in Spanish, use the following mnemonic:
On my house, you can see I'm a massive fan of 'Casablanca' (casa) because there is a mural of Humphrey Bogart and Ingrid Bergman on the side.
Casa is feminine, so it's la casa. Imagine a lady shaped house.
