You are all no doubt aware of the double linking device - On the one hand ... on the other (hand) ... used to contrast two ideas, for example:
On the one hand we could try that new restaurant on Park Street. On the other, we could just stay at home and order a pizza.
But can we use just on the other hand without the introductory On the one hand? Can we say:
We could try that new restaurant on Park Street. On the other hand we could just stay at home and order a pizza.
I asked some of my students this question the other day. How do you think they answered? How would you answer?
