Music: me coming back's something you'd never perceive
palindromické číslo (¡ ah ha!)
in catalonia (of all places!), and through catalan influence, in spain, and by extension in the spanish-speaking countries and portugal (through spanish), exists the specific word capicúa, originated by the two catalan words "cap", meaning head, and "cúa", meaning tail. the conjunction "i" (and) joins them to create a new word that explains in itself the symmetry. this word is widely used in the colloquial language, rather than palindromic number (mathematics) or palindrome, for words, phrases, or others.
