Many Americans learn Spanish. What's the use of Spanish? Is Spain rich? Why study?

Spanish is the official language, common language and commercial language of all Latin American countries (that is, America south of the United States) (except Brazil and French Guiana).

In other words, in order to build the United States into an American-style America, citizens can benefit greatly from learning Spanish, and they can also communicate with Hispanics (also called Latinos) in China.

If you are proficient in Spanish, it will be easier to learn Portuguese, French and Italian, all of which belong to Indo-European and Romans languages, and it will also facilitate communication with the whole of Europe.

And "photon000" has some misunderstandings about language learning. After all, language is just a tool, not a means of promotion and further study like China.
