What is a "derivative"?
A derivative is a word formed from an existing word by adding an affix or making changes that result in a new meaning or part of speech. This process often involves the addition of prefixes or suffixes to the base or root word. For example, the noun "happy" can be transformed into the adjective "unhappy" by adding the prefix "un-", or into the noun "happiness" by adding the suffix "-ness". Derivatives expand the vocabulary of a language and allow for the expression of different concepts and grammatical categories, enhancing communication by providing various forms and meanings related to a root word.
