"Diaeresis" Natural Recordings by Native Speakers
The diaeresis (also known as the umlaut) is a diacritical mark consisting of two dots (¨) placed above a letter, used to indicate that the letter or the combination of letters with which it is used are pronounced separately. For example, "Naïve" or "Coöperate". It is used to show that two adjacent vowels are to be pronounced as separate syllables, rather than being blended together as a diphthong.
Diadumenian is a rare Roman name that refers to the son of Macrinus, the Roman Emperor who ruled from 217 to 218 AD. The name Diadumenian is a combination of the Greek words "diaduma," meaning "printing" or "binding", and the suffix "-ian," which is a possessive form.
Diagenetic refers to the process of converting sediment into sedimentary rock, particularly in the transition from sediment to lithified rock. It can also refer to the chemical, physical, or biological changes that occur in sediment as it is buried and compacted, resulting in the formation of new minerals or textures.
