Derivation vs. Affixation: Know the Difference

Derivation is the process of creating new words from existing ones by adding affixes, while affixation is the act of adding prefixes, suffixes, or infixes to a word.
Derivation vs. Affixation

Key Differences

Derivation involves creating new words by adding, changing, or removing affixes, thus altering the meaning or grammatical category. Affixation, a part of this process, specifically refers to attaching prefixes, suffixes, or infixes to the base form of a word.
The outcome of derivation is a derived word with a new meaning or grammatical function, whereas affixation is the technical act of adding an affix to a root word, which can be part of derivation.
Derivation can change a word's part of speech, like turning a noun into an adjective. Affixation, in this context, is the method through which this change is achieved by adding relevant affixes.
In derivation, the focus is on the result of the process - a new word with altered meaning. In affixation, the emphasis is on the process itself - the act of adding an affix.
Derivation can involve multiple linguistic processes, including affixation, but affixation strictly refers to the addition of affixes without implying a complete transformation of the word.
