The first four letters of huevos sound like the word wave with an “O’s” sound at the end of the word.
If you think about it the letter “O” looks like an egg.
Therefore, you can draw a picture of a wave breaking on the shore of a beach with a bunch of eggs flying out of it.
This creative thought and image of a wave breaking at the beach with a bunch of “O” shaped eggs flying out of it will always remind you that the word huevos means eggs when you take your Spanish test.
