To understand why "ser" is used in this context, it is important to recognize the difference between the verbs "ser" and "estar." Both verbs can be translated to "to be" in English, but they are used in different situations. While "estar" is used to express temporary states or conditions, "ser" is used for more permanent characteristics.

In the sentence, "Yo ser alta," the subject "Yo" (meaning "I" in English) is describing their permanent characteristic of being tall. This characteristic does not change easily and is a part of their identity. Therefore, the verb "ser" is used to accurately convey this idea.

To determine which verb to use in a sentence, consider whether the characteristic being described is temporary or permanent. If it is a permanent quality, like height in this case, the verb "ser" is the appropriate choice.
