Subsequently, one may also ask, how is ë pronounced?
Ë with diaeresis is the easiest case to deal with. The diaeresis (the two dots) signifies that the underlying “e” is pronounced as /?/ (as “e” in “bet”, i.e. the open e), no matter what comes around it, and is used in groups of vowels that would otherwise be pronounced differently.
What is the meaning of Ë?

What is the E with two dots above it called?
You can also called it a ring. In Danish, Swedish and Norwegian the vowel with this sign over it it treated as a separate letter rather than as an accented one. The two dots, however, might be a diaeresis, as in naïve, or a trema, as in the French ambiguë, rather than an umlaut.
