title_body: How do you pronounce the ":" in Wede:i?
upvoted_answer: The phonology table shows it quite simply, it modifies the e to indicate that it is a long vowel. I don't know why the vowel table shows the dipthongs a:i and a:u but not e:i (or any others).
  
  Note that although this may seem to be a common colon, the actual IPA diacritic is two triangles, flat sides on the outside: U+02D0 ː. But as the colon doesn't have another meaning in the IPA and it's much easier to type, a lot of people just use it instead.
