What does a vowel suffix generally do to a base word?

A vowel suffix typically modifies the usage of the base word by transforming it into a different part of speech or altering its grammatical function. For example, when adding a vowel suffix like "-ing" to the base word "run," it converts the verb into a gerund, thereby changing how the word can be used in a sentence. Similarly, adding "-ness" to an adjective like "happy" creates the noun "happiness," which further changes the application of the word in language.

This process showcases the role of vowel suffixes in enriching the language by enabling words to take on diverse forms and uses, making them versatile within the context of speech and writing. Thus, the essence of a vowel suffix lies in its ability to modify the function of the base word rather than change its meaning entirely or have no effect.
