Inflection - Inflectional Morphology

Inflectional Morphology

Languages that add inflectional morphemes to words are sometimes called inflectional languages, which is a synonym for inflected languages. Morphemes may be added in several different ways:

• Affixation, or simply adding morphemes onto the word without changing the root,
• Reduplication, doubling all or part of a word to change its meaning,
• Alternation, exchanging one sound for another in the root (usually vowel sounds, as in the ablaut process found in Germanic strong verbs and the umlaut often found in nouns, among others).
• Suprasegmental variations, such as of stress, pitch or tone, where no sounds are added or changed but the intonation and relative strength of each sound is altered regularly. For an example, see Initial-stress-derived noun.

Affixing includes prefixing (adding before the base), and suffixing (adding after the base), as well as the much less common infixing (inside) and circumfixing (a combination of prefix and suffix).

Inflection is most typically realized by adding an inflectional morpheme (that is, affixation) to the base form (either the root or a stem).
