Alt. of 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 / 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Latin words with ae, it is mostly superseded by e. For most words found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.
