Bottom – el fondo
(Pronounced fohn-doh)
To remember that bottom is pronounced fohn-doh (fondo) in Spanish, use the following mnemonic:
At the bottom of the pond lived a beautiful fish – she was very fond of it after over (fondo) 20 years living there.
Fondo is masculine, so it's el fondo. Imagine an elephant falling into the bottom of a ravine and getting trapped.
