Definition

1. Noun:
   • A diacritical mark consisting of two dots (¨) placed over a vowel: This mark is used in various languages, most notably in German, to indicate that the vowel is to be pronounced as a separate syllable or with a different sound quality than it would be without the mark.
   • The separation of a single vowel or diphthong into two distinct syllables: In linguistics, "dieresis" can also refer to the phonological phenomenon itself, where a sound that is typically a single unit is pronounced as two.

Usage Examples

• Noun:
  • The German word "über" uses a dieresis over the 'u'.
  • In the name "Zoë," the dieresis indicates that the 'o' and 'e' are pronounced separately.
  • The poet used a dieresis in "coöperate" to show the separate pronunciation of the two 'o's.

Advanced Usage

• In poetry and historical texts: The dieresis is sometimes used in English poetry or older texts to indicate that two adjacent vowels are not a diphthong but form separate syllables, aiding in meter and pronunciation.
  • The archaic spelling "aërial" uses a dieresis.
• In linguistics: The term can describe the process or result of vowel splitting.
  • The dieresis in ancient Greek changed the pronunciation of certain diphthongs.

Variants and Related Words

• Diaeresis: This is an alternative, and often more common, spelling for the same mark and concept, particularly in British English.
• Umlaut: In the context of German, the two-dot diacritic is often called an "umlaut." While "umlaut" specifically denotes a sound change (fronting of a back vowel), the mark itself is visually identical to a dieresis. The distinction is primarily linguistic, not typographical.
• Trema: A synonym for the diacritical mark itself, used in languages like French and Greek.

Synonyms

• Separator (in the specific context of indicating separate vowel sounds).
• Diacritic (a general term for a mark added to a letter).

Related Phrases

• To place a dieresis: The act of adding this diacritical mark.
  • The editor had to place a dieresis over the 'e'.
