The Spanish verb "ser" is one of the most fundamental and complex verbs in the Spanish language, serving multiple purposes depending on the context in which it is used. At its core, "ser" translates to "to be" in English, but its application extends far beyond a simple translation due to the nuances of Spanish grammar and the distinction between "ser" and another verb that also means "to be," which is "estar".
Basic Uses of Ser

“Ser” is used to describe permanent or inherent qualities of something or someone, such as physical characteristics, nationality, occupation, or ownership. For example:
