Last week we had one of the 'to be' verbs in Spanish (ser). This week we have the other 'to be' verb - 'estar'. Tomorrow I will run through when to use which one. See previous posts in this series for more about conjugations.
Estar - to be
estoy = I am
estás = you are (sing. fam.)
está = he/she/it is, you are (sing. pol.)
estamos = we are
estáis = you are (pl. fam.)
están = they are, you are (pl. pol.)
