Definición y Significado de "affixation"

What is "affixation"?

Affixation is the process of adding prefixes, suffixes, infixes, or circumfixes to a base word or root to create new words or change the meaning of the original word. For example, in the word "unhappy", the prefix "un-" is added to the root "happy" to create a new meaning, indicating the opposite of happiness. Affixation allows for the expansion of vocabulary and can change a word's grammatical function, such as turning a noun into an adjective or a verb into a noun. This process is common in many languages and plays a key role in word formation and language structure.
