I have the rarest type of synesthesia, which means I can actually taste words. It’s called lexical-gustatory, and less than .2% of the population has it. I have to physically say the words out loud to taste them (so reading silently to myself won’t do it). When I was younger, I’d always repeat words that tasted good in my head, and I’d avoid saying words that tasted bad.”
Now I can mostly ignore it. It only happens if I speak, so I don’t taste from other people during conversations. For example, ‘Sam’ tastes like lemon juice mixed with salt, almost like a chili-lime flavor without the spiciness; ‘Jon’ tastes like raisins; and ‘Noah’ tastes like avocado
