I was commissioned to write an article on eponyms (words which derive from the names of people), and my brief was to ignore the eponyms that everyone knows, such as bloomers, hoover and boycott but to find others to write about. I delved into my dictionaries and came upon tawdry.
Tawdry, meaning cheap and nasty, or tacky, is an eponym, because the word derives from St Audrey, a 7th-century Anglo-Saxon princess of East Anglia and patron saint of Ely. Audrey was also known by the name Etheldreda. Tawdry is short for the now obsolete expression tawdry lace. Legend has it that Audrey, a religious woman, died of a tumour in her throat. She believed the tumour grew because she was being divinely punished for her love of fine silk and lace neck ornaments. In the 16th century the women of East Anglia would buy tawdry lace adornments and jewellery at annual fairs held in honour of their patron saint. In time cheap and tacky versions of the necklaces were produced and sold at a lower price, hence today's meaning of the word tawdry.
This story reminds me a bit of the derivation of sleazy.
