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 planning, my friends were planning. You always takes were, even when you talk to one person.
2. They were plan ❌
The Past Continuous needs both parts: was or were + the -ing form. They were plan forgets the -ing. They planning forgets were. The correct form is they were planning.
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.
