The word 'cataract' originates from the Latin word 'cataracta,' meaning 'waterfall' or 'portcullis.' In the context of the eye, it metaphorically describes the condition as a grating or barrier that slowly comes down, obscuring vision, much like a waterfall or portcullis.
'Zwodder' is a word from Somerset dialect that describes a drowsy, enjoyable state of slumberousness, often experienced when half-awake or half-asleep, especially in warm and dark conditions. It is associated with the 'dog days' of summer, a time of torpor and lethargy.
The term 'dog days' refers to the hottest period of summer and is linked to Sirius, the Dog Star, which rises with the sun during this time in the Northern Hemisphere. The name has nothing to do with dogs seeking shade but is instead tied to the astronomical phenomenon of Sirius's appearance.
Susie Dent was inspired to write 'Guilty by Definition' by her father, who always encouraged her to write fiction, and by her editor, who suggested a crime novel set in the 1930s in Oxford. Dent saw parallels between her work as a lexicographer and etymologist—digging for word origins—and the detective work in crime fiction. The novel also explores the darker side of Oxford and the motivations behind language.
The Oxford English Dictionary (OED) is a historical dictionary that tracks the journey of words from their first recorded use to their current meanings. Unlike other dictionaries, once a word is added to the OED, it is never removed. The OED is also unique in its extensive use of citations from literature, media, and other sources to document word usage over time. It is considered the 'mother of all dictionaries' and is continuously updated, with new words added regularly.
Volunteers have historically played a crucial role in the creation of the Oxford English Dictionary by submitting evidence of word usage on slips of paper. These contributions, often from diverse and colorful individuals, helped build the dictionary's extensive citation database. Even today, an army of readers continues to search for earlier evidence of words, contributing to the ongoing evolution of the OED.
The term 'secretary' originally referred to someone who kept secrets or confidential documents. In the context of lexicography, it highlights the role of lexicographers as 'secretaries of English,' entrusted with preserving and documenting the language. This idea is central to the plot of 'Guilty by Definition,' where mysterious letters task the lexicographers with decoding hidden messages.
The genius of Countdown’s dictionary corner Susie Dent is the master of the English language. Lexicographer and etymologist by training, she has spent 30 years on our screens explaining the history and origin of words on one of the world’s longest-running game shows, Channel 4’s Countdown.
In November 2024 Dent came to the Intelligence Squared stage to discuss her life-long love affair with the English language and how it has culminated in her debut crime novel Guilt by Definition — a glorious celebration of the English dictionary. As all good crime novels begin, it unfolds around a mysterious disappearance. And the protagonist, Martha Thornhill, Senior Editor of the Clarendon English Dictionary, uses words, and their peculiarly precise meanings, as clues in her quest to find out what really happened.
