Definition

Noun: A state of deep, serious, and often somewhat gloomy or absent-minded thought; a reverie or period of intense absorption in one's own thoughts, often to the exclusion of the external world.

Usage

This is a formal, somewhat literary, and now slightly old-fashioned term. It describes a person who is so lost in their own thoughts that they seem unaware of their surroundings. It often implies a pensive, meditative, or brooding quality.

Advanced Usage

• It can sometimes carry a connotation of melancholy or troubled thought, not just neutral concentration.

Variants and Related Words
