Don't say you are wrong, probably this is about diferent spanish usage since it varies from country to country and even more from continent to continent.

Daily language use is a very different thing to etymology.

Let me give you an example:

I'm learning Polish as a second language, and I love, love, love the Polish word for whale: wieloryb.

Why?

It's a contraction of the words for great/large and fish: wielki + ryba = wieloryb. Isn't that cute?

No Pole in their right mind thinks of "great fish" when you say "whale;" that's clearly nonsense.

And yet despite this, the history of the word remains.
