Now and then

Occasionally.I like to go to that restaurant now and then.

Now and again

Occasionally.Now and again we have pasta for dinner.

Nothing to write home about

Nothing exciting or interesting happened.a) "Did anything interesting happen during your holiday." b) "Nothing to write home about," I replied.

Nothing to speak of

Not many, not much.a) "Did you find any problems during the house inspection." b) "Nothing to speak of. Everything seemed to be fine."

Nothing to choose from

No choice.There was nothing to choose from when we went to the shoe sale in the afternoon.

Nothing short of (something)

To be almost the same as something.It was nothing short of a miracle that the young man survived the car accident.

Nothing of the kind

To be nothing like that.My boss thought that I was complaining but I told him that my comments were nothing of the kind.

Nothing if not (something)

Without doubt, certainly.The man is nothing if not punctual. He has never been late in his seven years with this company.

Nothing down

To not require a down payment.The young couple purchased their house with nothing down.
