Vowel Changes in German: Ablaut and Umlaut122

## Ablaut and Umlaut
Ablaut and Umlaut are two of the most important vowel changes in the history of the German language. These changes have had a profound impact on the phonology and morphology of German, and they continue to play a role in the language's development today.


Ablaut
Ablaut is a vowel change that affects the root vowel of a word. It is a regular change that occurs in certain grammatical forms, such as the present tense and the past participle. The most common ablaut patterns are:
* a > o
* e > i
* i > a
For example, the verb *singen* (to sing) has the following ablaut forms:
* Present tense: singt
* Past tense: sang
* Past participle: gesungen
Ablaut is not only a grammatical phenomenon; it also has a semantic function. In many cases, ablaut is used to distinguish between different meanings of a word. For example, the verb *tragen* (to carry) has the following ablaut forms:
* tragen (to carry something)
* trug (to carry something heavy)
* getragen (to carry something for a long distance)


Umlaut
Umlaut is a vowel change that affects the vowel of a syllable that is followed by an -i or -j. Umlaut is a relatively recent change in the history of German, and it is not as regular as ablaut. The most common umlaut patterns are:
* a > ä
* e > ä
* o > ö
* u > ü
For example, the noun *Mutter* (mother) has the umlaut form *Mütter* (mothers).
Umlaut is not only a phonological phenomenon; it also has a morphological function. In many cases, umlaut is used to mark the plural of a noun or the diminutive of an adjective. For example, the noun *Kind* (child) has the umlaut form *Kinder* (children), and the adjective *klein* (small) has the umlaut form *kleinere* (smaller).
