fedora

the word 'fedora' entered english in the late 19th century, borrowed from the french 'fé́dora', which itself was taken from modern greek 'phedora' (Φαιδώρα). this greek name is a feminine form derived from the ancient greek 'phaidros', meaning "bright" or "radiant". the term was originally the title of an 1882 victorien sardou play, whose heroine, princess fédora romanoff, wore a soft-brimmed hat. the association of the character's name with this style of headwear was so strong that it became the common noun for the hat itself, demonstrating a classic case of a proper noun transitioning into a generic term based on cultural reference.

this is a loanword adopted as a simplex unit from modern greek via italian. it does not contain separable morphemes within its current english spelling.
