“Fig” comes from the Latin “Ficus” — obvious enough!

But, curiously, the Spanish word is “Higado”. Huh?

This is just a simple example of the Initial F to H pattern. In lots of Latin words, the first F became an H when Latin evolved into Spanish. Think fact/hecho or hablar/fable.

An easy way to figure out what an H- word in Spanish is: change the initial H to an F and see what English word sounds similar.
