There are countless one-word palindromes in the English language, many of them common, such as Mom, Dad, poop, boob, sees, racecar, level, and rotor, as well as the names Bob, Otto, Ava, and Hannah. At their most base level, one-word palindromes signify a concept, and the words themselves are palindromic more by coincidence than anything else; they sound perfectly natural when spoken. Slightly longer phrase palindromes, like a red-eyed era and to prefer pot are evasive as naturally uttered speech and in fact probably have been spoken by many yet recognized by few to no listeners or speakers.
