to yourself, himself, etc.

to oneself

To the exclusion of anyone else. I have the house to myself this weekend, so I'm thinking of throwing a party. Now, that's private information, so just keep it to yourself.

(all) to yourˈself, himˈself, etc.

for only you, him, etc. to have, use, etc: The boss was away last week so we had the office to ourselves.
