demijohn: [18] Demijohn ‘large globular bottle’ has no connection with half of the common male forename. It arose through a process known as folk etymology, by which an unfamiliar or slightly outlandish foreign word is deconstructed and then reassembled using similar-sounding elements in the host language. In this case the source was French dame-jeanne, literally ‘Lady Jane’, a term used in French for such a container since the 17th century.
