What does derrick mean?
A derrick is a tall, tower-like framework of steel or timber used either for hoisting heavy loads or, most famously, for supporting the drilling apparatus above an oil well. The word originated as the nickname of Thomas Derrick, an early seventeenth-century English executioner, whose gallows came to bear his name; the term was then transferred to any similar upright frame used for lifting. Today derricks are central images of the petroleum industry, appearing on rigs on land and offshore, where they house the machinery that raises and lowers drill pipe. The word also applies more generally to cranes and hoisting frames mounted on ships, docks, and building sites. Because of its industrial associations, "derrick" often evokes energy production, labor, and large-scale engineering. Its plural form is simply "derricks," and the related term "derrickman" refers to a crew member who works atop the rig.
A tower framework over an oil well that supports the drilling equipment and the raising and lowering of drill pipe.
"The derrick rose nearly a hundred feet above the drilling floor."
This sense dominates in American English and in coverage of the oil and gas industry.
A lifting apparatus consisting of a mast or boom fitted with pulleys and ropes or cables for hoisting heavy weights.
"Dockworkers used a derrick to swing cargo crates onto the ship."
Regular plural; used when referring to multiple rigs or hoisting structures, as across an oil field or harbor.
"Dozens of derricks dotted the landscape around Midland."
The word 'derrick' is named after Thomas Derrick, a 17th-century London executioner — the gallows he operated were nicknamed after him before the name migrated to oil rigs.

Etymology of derrick
The word derives from the name of Thomas Derrick, an English executioner active in London around the turn of the seventeenth century; gallows of his design became known as "derricks." By the early seventeenth century the term had broadened to mean any upright frame used for hanging or hoisting. As mechanical lifting technology spread through shipping and industry, "derrick" came to denote cranes and hoisting masts generally. When commercial oil drilling emerged in nineteenth-century America, the distinctive towers built over wells adopted the same name, cementing its modern association with the petroleum industry. Being an eponym, it has no true cognates from another language.
