Spanish is the most translated language in the US. While Spanish is one of the easier languages to learn, technical texts are often considered difficult to translate into Spanish. One of the main reasons given is that there is no single variety of Spanish. There are, in fact, major differences between the Spanish of Spain and, say, South America.
But what are pharmaceutical and medical device companies to do? Do you need to provide multiple Spanish translations if you wish to market services to the general Hispanic population in the US or to sell your products to Spanish speakers in both South America and Spain? The experts will tell you that you must write specifically in the Spanish of your target audience. In other words, only Mexican Spanish will do for Mexicans.
The experts are wrong.
