Common mistakes to avoid
1. You was / They was ❌
Use was only with I, he, she and it. Use were with you, we, they and plural nouns: you were changing, my friends were changing. You always takes were, even when you talk to one person.
2. They were change ❌
The Past Continuous needs both parts: was or were + the -ing form. They were change forgets the -ing. They changing forgets were. The correct form is they were changing.
3. I was knowing ❌
State verbs (know, understand, want, need, like) are not normally used in the continuous. In the past, use the Past Simple: I knew the answer, not I was knowing the answer.
