what is a sufix

A suffix is an affix that is added to the end of a word to modify its meaning or change its grammatical function. Suffixes are a type of morpheme, which are the smallest units of meaning in a language. Common examples of suffixes include "-ly" and "-ness". Suffixes can change the tense, part of speech, or meaning of a word. For example, the suffix "-ed" can be added to the end of a verb to indicate past tense, as in "walked" or "talked". Similarly, the suffix "-able" can be added to the end of a verb to create an adjective, as in "readable" or "drinkable". Suffixes can also be used to create new words, such as "happiness" or "carelessness".
