Keep a secret for / to yourself

[ratóncolorao]

Hello,

Can you please help me with the following sentence:

Can you keep a secret.........yourself?

What should I write: for or to

It is a class exercise and I have only this sentence with no context at all. We must fill the gap.

Thank you for your help

I would say the answer is 'to'.

Though normally, we say "Can you keep a secret?" or "Can you keep this (the secret) to yourself?"
