Umlaut
Related Category: Language and Linguistics
(

m´lout) [Ger.,=transformed sound], in
inflection, variation of vowels of the type of English
man to
men. In this instance it is the end product of the effect of a
y (long since disappeared) that was present in the plural; the
y caused the vowel before the
n to be pronounced higher and more forward in the mouth in the plural than in the singular; eventually there was replacement of the vowel in the plural. Other examples are
mouse, mice; tooth, teeth; to fall, to fell; doom, deem. Umlaut is also called mutation and inflection. For the variation of
sing, sang, see
ablaut. Umlaut is also the name for the diacritical symbol placed above a vowel to indicate a sound change in Germanic languages, as in the German
Fräulein and the Swedish
fröken (see
accent).
