derivation of the word

[mustache]

picadilly

[Quizmonster]

A piccadill, without the capital and final 'y', was a sort of slashed collar popular in the 17th/18th centuries. There was a house in the parish of St Martin in the Fields, London, nicknamed 'Piccadilly Hall'. It got this name because it supposedly belonged to a Mr Higgins, a tailor, who had made his fortune ny making these collars. It is from that name that present-day Piccadilly got its name.

[Upforit]

I thought it was a tangy yellow mix of mustard with some vegetables thrown in, delicious with cheese. But I also thought General Knowledge won the Battle of the Encyclopaedias

[grandmabundy]

I believe it is derived from the word peccadillo - you can look that one up!

Quizmonster has it - except there was one 'L' (picadils) and the tailor was Robert Baker and he was around in the 16th/17th centuries.
