This week another essential and very irregular verb - 'ser', meaning 'to be'. Ser is actually one of two verbs in Spanish for 'to be' and the choice of which one to use can be quite subtle. More on that in future posts. See previous posts in this series for more about conjugations.
Ser - to be
soy = I am
eres = you are (sing. fam.)
es = he/she/it is, you are (sing. pol.)
somos = we are
sois = you are (pl. fam.)
son = they are, you are (pl. pol.)
