Hi you!
if you are looking for the explanation how to use WAS and WERE
here is:
you will use Was (the verb is in past form, when you use was you are talking about just 1 person,thing or Animal)
for Example:
Present Form Past Form
Personal Pronoun Verb to be Personal Pronoun Verb to be
I am I was
You are you were
He/ She/ it is She/ He/ it were
We are We were
They are They Were
Note : Was = is something you did in the PAST (1 person/Singular)
Were = is something you and your friends did in the PAST (2 o More People/Plural)
I was eating a hamburguer
Michael, I and Rosy were playing Pocker last night.
Michael, I ,Rosy = They (Personal Pronoun)
if you have any question please do let me know
