What does unreflected mean?
Unreflected is an adjective with two related but distinct uses. In its figurative sense, it describes an action, decision, or response made without careful thought or self-examination, often carrying a slightly formal or critical tone. For example, an unreflected reaction may seem impulsive or unpremeditated. In its literal and technical sense, unreflected describes light, sound, or another wave that has not bounced from a surface or been redirected. The distinction lies in the meaning of reflection: in the figurative use it means thinking over something, while in the physical use it means the redirection of a wave. The word is most useful when precision matters, although reflective, considered, or thoughtful often provide more idiomatic alternatives for the figurative sense.
