Perhaps you're thinking of a different scenario, such as:
* Spanish speakers in other countries: There are many Spanish speakers in countries like the United States, Mexico, and Argentina. While these people are of Spanish descent, they may speak a different dialect of Spanish or have adopted English as their primary language depending on the context.
* Historical changes in language: Languages evolve over time, and there have been periods in Spanish history where certain dialects or forms of the language have been more prevalent. For example, in the Middle Ages, there were various regional languages spoken in Spain, which eventually merged into the modern Spanish language.
* Loss of language due to assimilation: In some cases, immigrants to a new country may lose their native language and adopt the dominant language of their adopted homeland. This is a common phenomenon worldwide, not specific to Spanish speakers.
