Short answers
To avoid repetition in conversations, we often use short answers.
- "Are you John?" "Yes, I am [John]."
- "Did you lock the door?" "No, I didn't [lock the door]."
A short affirmative answer cannot end with a contraction of the verb be.
- Are you English?
- Yes, I am. / No, I am not. / No, I'm not.
NOT: Yes, I'm.
When an auxiliary verb is used in the question, the same auxiliary verb is used in the short answer.
- "Do you like beer?" "Yes, I do." / "No, I don't."
- "Would you like a beer?" "Yes, I would." / "No, I wouldn't."
- "Can you swim?" "Yes, I can." / "No, I can't."
- "Will you remember?" "Yes, I will." / "No, I won't."
- "Did you see Oscar?" "Yes, I did." / "No, I didn't."
- "Are you enjoying the meal?" "Yes, I am." / "No, I am not." / No, I amn't.
- "Were you living in London?" "Yes, I was." / "No, I wasn't."
- "Have you seen Wally?" "Yes, I have." / "No, I haven't."
