{{stub}}

A '''trema''', also known as '''diaeresis''', is a diacritic used to mark adjacent vowels as being in separate syllables rather than [[dipthong]]s, for example in the Dutch 'vacu&#xFC;m.' It primarily appears in languages and in cases where there may be confusion.

A trema falls away when a word is hyphenated on such a syllable border. 



'''Umlaut''' is generally interpreted as the diacritical mark that indicates the alteration of a vowel (Umlaut is German, meaning something like 'sound alteration').

More specifically the phonological umlaut, a vowel alteration (I-mutation, specifically{{verify}}).

Umlaut is also sometimes (erroneously) used to refer to the wider concept of [[apophony]].


While we took the term from German, the [https://en.wikipedia.org/wiki/Germanic_umlaut Germanic umlaut] is now a specific example of linguistic umlaut.
