Ocean – el océano
(Pronounced oh-theh-ah-noh)
To remember that ocean is pronounced oh-theh-ah-noh (océano) in European Spanish, use the following mnemonic:
In the middle of the ocean they found a raft with a bunch of old thespians singing along to a piano (océano).
Océano is masculine so it's el océano. Imagine an elephant rowing a boat across an ocean.
