- a historical change in the sound of a vowel, caused by its assimilation to another vowel or semivowel originally occurring in the next syllable but later sometimes lost; mutation: in English, the differences of vowel in certain singulars and plurals (Ex.: foot—feet, mouse—mice) or in certain causative verbs and the words from which they are derived (Ex.: gold—gild) are due to the effects of umlaut on the second word of each pair
- a vowel resulting from such assimilation
- the diacritical mark (¨) placed over a vowel, esp. in German, to indicate umlaut
Origin of umlautGer, change of sound (; from um, about + laut, sound, akin to loud): coined (1774) by F. G. Klopstock, German poet, but first used in special senses by Jakob Grimm (1819)

Origin of umlautGerman : um-, around, alteration (from Middle High German umb-, from umbe, from Old High German umbi; see ambhi in Indo-European roots) + Laut, sound (from Middle High German l&umacron;t, from Old High German hl&umacron;t; see kleu- in Indo-European roots).
(plural umlauts or umlaute)
- (linguistics) An assimilatory process whereby a vowel is pronounced more like a following vocoid that is separated by one or more consonants.
- (linguistics) The umlaut process (as above) that occurred historically in Germanic languages whereby back vowels became front vowels when followed by syllable containing a front vocoid (e.g. Germanic lÅ«siz > Old English lÈ³s(i) > Modern English lice).
- (linguistics) A vowel so assimilated.
- (orthography) The diacritical mark (Â¨) placed over a vowel, usually when it indicates such assimilation.
- Although this symbol has the same form as the diaeresis/dieresis, it has as a different function and so in standard and technical usage these two terms are not interchangeable. The term for the diacritic mark, as opposed to its function, is trema.
- When spelling a German word out loud, one can say “(vowel) umlaut" or “umlauted (vowel)". e.g. “a umlaut" or “umlauted a" (Ã¤). (German practice is to say “a Umlaut", or more commonly to pronounce the letters, so the name of "Ã„" is [É›Ë], just as "A" is [aË] and "B" is [beË].)
- In alphabetic orders, "Ã¤, Ã¶, Ã¼" are treated as "a, o, u" in German (so the word lÃ¼gen comes directly after the word lugen). In other languages, such as Swedish, the umlaut letters may have their own position in the alphabet.
- The usual English plural is umlauts, but the form umlaute (after the German) has seen some use. It is quite rare, however.
(third-person singular simple present umlauts, present participle umlauting, simple past and past participle umlauted)
- To place an umlaut over a vowel.
