Respuesta :

Soy (yo form, present tense) - use when describing traits about yourself (permanent traits, not thoughts/feelings/locations/etc)

Era (yo/el/ella/usted form, past tense) - directly translates to 'was.' use when describing something in the past


Yo - soy

Tú - eres

Él, Ella, Ello, Uds - es

Nosotros (as) - somos

Vostros (as) - sois

Ellos, Ellas, Ustedes - son

You use ser when you are telling time, descriptions, occupation, and nationality

You would use estar when you are telling a place or location, and feelings
