What is derivation?

 

Definition
 

Derivation is the formation of a new word or inflectable stem from another word or stem. It typically occurs by the addition of an affix.

 

The derived word is often of a different word class from the original. It may thus take the inflectional affixes of the new word class.

Discussion
 

In contrast to inflection, derivation

 
  • is not obligatory
  • typically produces a greater change of meaning from the original form, and
  • is more likely to result in a form which has a somewhat idiosyncratic meaning.
  • often changes the grammatical category of a root
Examples (English)
 
  • Kindness is derived from kind.
  • Joyful is derived from joy.
  • Amazement is derived from amaze.
  • Speaker is derived from speak.
  • National is derived from nation.
Characteristics
 

Derivational operations

 
  • tend to be idiosyncratic and non-productive
  • do not occur in well-defined 'paradigms,' and
  • are 'optional' insofar as they

    • shape the basic semantic content of roots and
    • are not governed by some other syntactic operation or element.
Kinds
  Here are some kinds of derivation:
 
 

Here are some kinds of derivational operations:

 
  • Operations that change the grammatical category of a root

    Example: Nominalization (English)

    Verbs and adjectives can be turned into nouns: amaze >amazement, speak >speaker, perform >performance, soft >softness, warm >warmth

  • Operations that change the valence (transitivity) of a root, and

    Example: Causation (Swahili)

    kula 'to eat' > kulisha, 'to feed'
