She has all her Marbles : What does this sentence mean?
By Geoff, Poland - 6th Nov. 2007
When you say that someone has all his/her marbles, you mean that he/she is mentally sound. This word is used figuratively and in the formal context. Many literary giants use this word quite frequently.
• My neighbor is nearly 90 years old, but she hasn’t lost her marbles.
• If you are forced to stay in your apartment for another week, I’m sure you will lose your marbles.
