Say any word enough times and it turns into meaningless noise

Stare at or repeat a word for about three minutes and it stops feeling like a word at all — just a strange sound. Psychologists Elizabeth Severance and Margaret Floy Washburn documented this in 1907, decades before the phenomenon got its modern name, 'semantic satiation,' from a 1962 study on repeated stimulation.
