Etymology: Watson is a patronymic surname, built from the given name Wat, a pet form of Walter, plus the suffix "-son," meaning "son of." So a Watson was, originally, the son of a man called Wat. Surnames of this kind were common across medieval England, where many family names began as a father's first name with a "son" attached. The name's fame today comes almost entirely from Arthur Conan Doyle's Sherlock Holmes stories, in which Dr. John Watson serves as Holmes's companion and chronicler. Because the stories were widely read, the surname became closely tied in many readers' minds to the loyal, plain-spoken sidekick, a figure whose name now evokes a faithful assistant as much as a family line.

Synonyms: assistant, helper, sidekick, companion
