\[AE]\ or Ae \Ae\
A diphthong in the Latin language; used also by the Saxon
writers. It answers to the Gr. ai. The Anglo-Saxon short [ae]
was generally replaced by a, the long [=ae] by e or ee. In
derivatives from Latin words with ae, it is mostly superseded
by e. For most words found with this initial combination, the
reader will therefore search under the letter E.
