The phrase "in a brown study" means to be lost in thought or deep in contemplation. It is often used to describe someone who is quiet and introspective, perhaps even a bit melancholy. This phrase is most often used in a literary or formal context, and may not be very common in everyday conversation. However, it can be a useful expression to use when discussing characters in books or movies, or when trying to convey a sense of introspection or deep thoughtfulness in your own writing.
