EOLIC, or EOLIAN, in grammar, denotes one of the five dialects of the Greek tongue. It was first used in Bæotia; whence it passed into Eolia, and was that which Sappho and Alceus wrote in. The Eolic dialect generally throws out the aspirate or sharp spirit, and agrees in so many things with the Doric dialect, that the two are usually confounded together.
The Eolic digamma is a name given to the letter F, which the Eolians used to prefix to words beginning with vowels, as Êous, for Êous; also to insert between vowels, as Êus, for Êus.
