The phrase "at liberty" means that someone is free to do whatever they want, without any restrictions or limitations. It is usually used in the context of being released from a situation where there were previously restrictions or someone was under someone else's control, such as being released from jail, being let out of class, or finishing a job. It can also be used to describe a state of being where there are no limitations, such as being "at liberty" to choose what to do with one's time or resources.
