"Brought up rear" is an idiomatic expression used to describe someone or something that is in the last position or is lagging behind others in a particular group or activity. It generally refers to the act of being at the end of a line or procession, essentially occupying the backmost position.
The phrase can be applied in various contexts, such as in a race, where the person "bringing up the rear" is the slowest or least advanced participant, or in a military formation, where the phrase denotes the soldier who is positioned at the back end. Additionally, it may describe someone who is chronically late, consistently coming last to a gathering or event.
Figuratively, "brought up rear" can also be used metaphorically to depict a person or entity being the last to adapt or adopt new ideas, methodologies, or technologies. In this sense, the expression implies a lack of progress or innovation, as the individual or group is seen as being resistant to change and lagging behind their peers.
Overall, "brought up rear" connotes a position of trailing or being left behind in a literal or metaphorical sense. It depicts a person or thing that is situated at the end, either physically or metaphorically, and often conveys a sense of inadequacy, backwardness, or reluctance to embrace progress.
