Fanne

Fanne was an obsolete term for a female fan dating from the days when there weren't very many. It didn't survive, being replaced pretty universally by femmefan in the 1960s, tho it lasted a bit longer than firl.

From Fancyclopedia 2, ca. 1959

(pronounced "fan"). A female fan; also femmefan. Nancy Share tried to introduce Firl, but this didn't catch on. Feminine objection to this term is caused by clods giving the silent E full value (of Fanspeak).

From Fancyclopedia 1, ca. 1944

Pronounced same as "fans", but used in written to mean fem fans.
