Scrabble?! DIERESE

Definitions of DIERESE in various dictionaries:

The diaeresis ( dy-ERR-i-sis; plural: diaereses; also spelled diæresis or dieresis and also known as the tréma or trema) and the umlaut are two homoglyphic diacritical marks that consist of two dots ( ¨ ) placed over a letter, usually a vowel. When that letter is an i or a j, the diacritic replaces the tittle: ï.The diaeresis and the umlaut are diacritics marking two distinct phonological phenomena. The diaeresis represents the phenomenon also known as diaeresis or hiatus in which a vowel letter is pronounced separately from an adjacent vowel and not as part of a digraph or diphthong. The umlaut (), in contrast, indicates a sound shift. These two diacritics originated separately; the diaeresis is considerably older. Nevertheless, in modern computer systems using Unicode, the umlaut and diaeresis diacritics are identically encoded, e.g. U+00E4 ä LATIN SMALL LETTER A WITH DIAERESIS (HTML ä · ä) represents both a-umlaut and a-diaeresis (much like the hyphen-minus code point represents both a hyphen and often a minus sign). The same symbol is also used as a diacritic in other cases, distinct from both diaeresis and umlaut. For example, in Albanian and Tagalog ë represents a schwa.
