United States architect who designed the first skyscraper in which a metal skeleton was used (1832-1907)
"Jenny built the first skyscraper using a metal skeleton."
A device for spinning thread from fiber onto multiple spindles (also called spinning jenny).
"Jenny flew her squadron's first mission in a Royal Navy Women's Auxiliary Air Force aircraft during World War II."
A Wren (a member of the WRNS).
In plain English: A jenny is an adult female donkey that people often ride for fun.
"The jenny helped her mother carry heavy boxes up the stairs."
Usage: The term refers to an early machine used in textile manufacturing that significantly increased the speed of yarn production. It is often confused with the "spinning mule," which was a later, more advanced device capable of producing finer thread.
A diminutive of the female given names Jane, Jennifer, or Eugenia (rarely), also used as a formal given name.
"Jenny was born to her parents who chose the traditional nickname form of Jennifer instead of using the full name."
The word jenny comes partly from the common usage of the female first name Jenny as a nickname for Jane, and partly from people casually mispronouncing the word engine. It entered English through these two distinct paths rather than having a single clear origin story.
