Imperceptible

Imperceptible describes something that is so slight, subtle, or gradual as to be difficult or impossible to perceive or notice by the senses or the mind. This can refer to changes in temperature, minute shifts in behavior, or nearly invisible alterations in appearance. The term highlights the limits of human observation and emphasizes the importance of keen awareness or specialized instruments to detect such subtle phenomena.
