yo: era

tú: eras

él/ella/usted: era

nosotros/-as: éramos

vosotros/-as: erais

ellos/ellas/ustedes: eran

Example: "I would be rich if I sold this product," Yo sería rico si vendiera / vendiese este producto.

yo: sería

tú: serías

él/ella/usted: sería

nosotros/-as: seríamos

vosotros/-as: seríais

ellos/ellas/ustedes: serían


, The future indicative form of "ser" describes a concrete state of being that will definitely exist in the future.

yo: seré

tú: serás

él/ella/usted: será

nosotros/-as: seremos

vosotros/-as: seréis
