Function of inflectional ending s

An inflectional ending is a suffix added to a word to indicate grammatical information such as tense, number, person, or case. The main function of inflectional endings is to modify the meaning or form of a word to show its grammatical relationship to other words in a sentence. This can help convey information about the subject, object, or action being described. Inflectional endings typically do not change the basic meaning of a word, but they can alter its grammatical function.
