by myself

by (oneself)

1. Alone. Because there's usually so much going on with the kids, I really enjoy spending a quiet Saturday night by myself.2. Through one's own efforts alone. You can't move that table all by yourself! Here, let me help you. My little girl loves to get dressed by herself, so tutus and cowboy boots have become the norm around here.See also: by

 1. with no one else present; alone. I sat at the table by myself. I will not be at the party. I will be at home by myself tonight. 2. without the help of anyone else. I did it all by myself. Can you eat that whole pie by yourself?See also: by, myself
