In Spanish, unlike English, there is a normative reference authority that establishes the standards for "correct" Spanish, which is the Real Academia Española (RAE). Apart from the nuances and opinions that exist on the "correctness" of a language, there are two interesting tools for the student of Spanish: on the one hand, the Diccionario de la Lengua Española (https://dle.rae.es/) and on the other, the Diccionario Panhispánico de dudas (https://www.rae.es/dpd/), which aims to provide answers, in a clear and well-argued way, to the most common doubts that arise in the use of Spanish today.
