The Encyclopædia Brittanica still uses the symbol "æ". However, I still hear everyone pronounce it as "Encyclo pee dia", when their spelling suggests more along the lines of "Encyclo pah dia" or "encyclo pay dia". In a more general sense, should æ or Æ always be pronounced as a long e sound? When I see it used, it is in dæmon, æther, or æon.
The wikipedia page makes it clear that they should be pronounced with another sound along the lines of ah or eh... confusing because I want to pronounce it as "ai" or "ay". Given the name "Aion" as a recent videogame, and the common pronunciation of a CS mailer-daemon as "Daymon", clearly others behave the same way.
The problem lies in that æ used to be pronounced as ah/eh, and now seems to be pronounced as ay. Encyclopædia is the only exception... being pronounced as ee?
How do I pronounce it when seen in English? ee, ay, or ah/eh?
