* Spanish is one language: While there are regional variations in accent, vocabulary, and grammar, these are considered dialects of the same language. Think of the difference between British English and American English – they're both English, just with some variations.
* Dialects are part of a continuum: There's no clear dividing line between dialects, making it hard to count how many there are. It's more about a spectrum of variation.
* Focus on speakers, not dialects: The most relevant statistic is the number of Spanish speakers worldwide, which is estimated to be around 570 million.
So, instead of "Spanish languages," it's more accurate to talk about the number of Spanish speakers, or the regional variations within the Spanish language.
