For several years, a pair of mallard ducks have nested in the New Court of Corpus, probably based on its academic credentials and excellent foliage. The annual sight of the Corpus ducklings and their subsequent herding to the Cam occurred yesterday to great fanfare, as the entire College stopped what they were doing to watch.
The medieval theory of the duck was that it was named ans in Latin after its constancy (assiduitate) in swimming (natandi). If you look closely, this is described in the first sentence of the section on ducks in the Peterborough bestiary (MS 53, 14th c.), starting with the historiated letter ‘A’:
However, the name likely came from an Indo-European root word which was also visible in the Old English word for duck : enid. The Corpus Glossary (MS 144, early 9th c.) shows the translation of Latin aneta for Old English enid:
The modern English word for duck came from the original Anglo-Saxon verb, dúcan, meaning to dive or duck in the modern sense. The word was already in use for the bird by the late Anglo-Saxon era, but continued in tandem with enid or ende through the 15th c.
