Is there a word that describes a word that makes you feel the thing you are describing as you say it?
Ideophone
'A vivid representation of an idea in sound. A word, often onomatopoeic, which describes a predicate, qualificative or adverb in respect to manner, color, sound, smell, action, state or intensity.’
Ideophones evoke sensory events.
Example: "twinkle: the glow of something sparkling or shiny."
We say, her eyes twinkled merrily or we say wow! and our mere saying it makes us express admiration or surprise.
