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 becoming, my friends were becoming. You always takes were, even when you talk to one person.
2. Always add -ing
In the Past Continuous, the verb after was or were always ends in -ing: they were becoming. Without -ing, they were become is not the Past Continuous, and the meaning changes. Without was or were, they becoming is wrong.
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.
