The term 'FEMININE Ending' refers to a set of suffixes that are commonly used to indicate a FEMININE form of a word. The most common of these suffixes are ESS (3 letters), ENNE (4 letters), ETTE (4 letters), INE (3 letters) and TRIX (4 letters). These suffixes are often used to create a FEMININE version of a noun, such as 'PRINCESS' or 'ACTRESS'. They can also be used to create adjectives, such as 'FEMININE' or 'DAINTY'. In some cases, the suffixes can also be used to create verbs, such as 'DOMESTICATE' or 'FEMINIZE'.
