Ë, ë (e-diaeresis) is a letter in the Albanian, Kashubian, Emilian-Romagnol and Ladin alphabets. As a variant of the letter e, it also appears in Acehnese, Afrikaans, Dutch, Filipino, French, Luxembourgish, the Abruzzese dialect of the Neapolitan language, and the Ascolano dialect. The letter is also used in Seneca, Taiwanese Hokkien, Turoyo and Uyghur when written in Latin script.
In Afrikaans, the trema (Afrikaans: deelteken, [ˈdɪəl.tɪəkən]) is mostly used to indicate that the vowel should not be diphthongised, for example geër ("giver") is pronounced [χeər], whilst geer (a wedge-shaped piece of fabric) is pronounced [χiːr]. There are some cases where the deelteken does nothing to the pronunciation, like in reën ("rain"), which is pronounced [reən]. The non-existent word *reen would be pronounced the same. The deelteken in this case has only a historical background; the archaic form of reën is regen and the deelteken indicates that the g was removed. Some older people still pronounce reën in two syllables ([ˈreː.ən]).
The deelteken does exactly what it says (deelteken being Afrikaans for "separation mark"). It separates syllables, as it indicates the start of a new one. An example of this is the word voël ("bird"), which is pronounced in two syllables. Without it, the word would become voel ("feel"), which is pronounced in one syllable.
Ë is a phonetic symbol also used in the transcription of Abruzzese dialects and in the Province of Ascoli Piceno (the ascolano dialect). It is called "mute E" and sounds like a hummed é. It is important for the prosody of the dialect itself.
Use of the character Ë in the English language is relatively rare. Some publications, such as the American magazine The New Yorker, use it more often than others. It is used to indicate that the e is to be pronounced separately from the preceding vowel (e.g. in the word "reëntry", the feminine name "Chloë" or in the masculine name "Raphaël"), or at all - like in the name of the Brontë sisters, where without diaeresis the final e would be mute.
Ë appears in words like French Noël and Dutch koloniën. This so-called trema is used to indicate that the vowel should not be diphthonged. For example, Noël is pronounced [nɔɛl], whilst *Noel would be pronounced [nœl]. Likewise, "koloniën" is pronounced [koːˈloːniən], whilst "*kolonien" would be pronounced [koːˈloːnin].
In many editions of Latin texts, the diaeresis is used to indicate that ae and oe form a hiatus, not a diphthong (in the Classical pronunciation) or a monophthong (in traditional English pronunciations). Examples: aër "air", poëta "poet", coërcere "to coerce".
In Luxembourgish, ⟨ë⟩ is used for stressed schwa /ə/ like in the word ëmmer ("always"). It is also used to indicate a morphological plural ending after two ⟨ee⟩ such as in eeër ("eggs") or leeën ("lay").
In the romanization of Syriac, the letter Ë gives a schwa. In some grammatical constructions, it is a replacement for the other, original vowels (a, o, e, i, u). Example words that have Ë: knoṭër ("he is waiting"), krëhṭi ("they are running"), krëqdo ("she is dancing"), sxërla ("she has closed"), gfolëḥ ("he will work"), madënḥo ("east"), mën ("what"), ašër ("believe"). Turoyo and Assyrian languages may utilize this diacritic, albeit rarely.
In Tagalog and its standardized form Filipino, Ë is used to represent the schwa, particularly in words originating from other Philippine languages, for instance Maranao (Mëranaw), Pangasinan, Ilocano, and Ibaloi. Before introduction of this letter, schwa was ambiguously represented by A or E.
