Ages ago, I asked what the term is for the belief that one belongs to a branch of humanity that is separate and superior to others. I still haven't found the answer.
Also, I often want to use a word that describes singing without lyrics. "Vocalisation", "non linguistic syllables" and "non-lexical vocables" seem acceptable but not exactly likely to roll off the tongue.
Also, is there a term for when you learn a new word or phrase and then suddenly notice it everywhere?
