Etymology
'non-palindrome' originates from English, formed by prefixing 'non-' (from Latin 'non' meaning 'not') to 'palindrome', where 'palin-' comes from Greek 'palin' meaning 'again' and 'dromos' meant 'running or course'.
'palindrome' was coined in Modern English from Greek elements 'palin' + 'dromos' and entered English usage via scholarly Latin/French formations; 'non-' as a negative prefix has long been used in English to form negatives, producing 'non-palindrome' to mean 'not a palindrome'.
Initially the Greek elements together suggested the idea of 'running back again'; over time 'palindrome' came to mean a word or sequence that reads the same backward and forward, and adding 'non-' produced the modern meaning 'not a palindrome'.
