What's New

● Etymologies (word origins)
You will find a clear and brief account of the origins, history, and sense-development of a major part of the modern English vocabulary.
For example, you will learn that the word 'quarantine' comes from Italian quarantina ‎(“forty”), from quarantina giorni ‎(“forty days”). Originally when a ship arriving in port was suspected of being infected with a malignant, contagious disease, its cargo and crew were obliged to forego all contact with the shore for a period of around forty days.
