The term 'Palindromic Suffix' refers to a suffix that is spelled the same forwards and backwards. Two examples of palindromic suffixes are 'ette' (4 letters) and 'ese' (3 letters). These suffixes are often used to indicate a feminine or masculine form of a word, respectively. For example, the word 'POET' can be changed to 'poetesse' by adding the palindromic suffix 'ette'. Similarly, the word 'prince' can be changed to 'princesse' by adding the palindromic suffix 'ESSE'.
