Interest – el interés

(Pronounced een-teh-rehs)

To remember that interest is pronounced een-teh-rehs (interés) in Spanish, use the following mnemonic:

They couldn't help but show an interest in her because the teen looked like an extra-terrestrial (interés).

Interés is masculine, so it's el interés. Imagine an elephant that has an interest in extra-terrestrials.
