Now, I am going to put a question to you, and one very much to the purpose too.

Some members simply wanted to get back to the purpose of the group.

But to what purpose, when others would take their place who felt the same.

But you're not the only people who have been called to a purpose.

He'd been ready to give up his life, but not to live on to be used to another's purpose.

I have tried hard for you, but all to no purpose.

I also thought a good deal, to no great purpose.

It would not be to my purpose here to give its name.

It would be a lot of work to no purpose.

In some way he might turn the thing to his own purposes.
