Can you describe a sensation without feeling it first?

Blind or colorblind people can describe colors and use expressions like “green with envy” or “feeling blue.” A hearing-impaired person can also say those same vibrant hues are “loud.” But many linguists and cognitive neuroscientists have assumed that somatosensation—touch, pain, pressure, temperature, and proprioception, or the sense of where your body is oriented in space—is fundamental for understanding metaphors that have to do with tactile sensations. Understanding expressions like “she is having a tough time” or “that class was hard,” it was believed, requires previous experience with those sensations to extend their meaning to metaphors.
