Definition: A device for spinning thread from fiber onto multiple spindles (also called spinning jenny).

Alright class, settle down, let’s take a look! Today we’re tackling a word – “Jenny.” It might seem simple, but it holds a fascinating piece of history. The dictionary tells us, "A device for spinning thread from fiber onto multiple spindles…" That's the core meaning, you see? Think about this: back in days long ago, making cloth was hard work! People would spin yarn by hand, one thread at a time – a slow and steady pace. Then came Mary Aiken Jenyns , a clever woman from England. She invented the "spinning jenny" around 1773. It’s named after her, you know! “Jenny” is short for ‘Spinning Jenny,’ a machine that could spin multiple threads at once - quite a feat, it's true! It really sped things up and made cloth production much more efficient. So, remember: “Jenny” refers to this important invention – a game-changer in the textile industry. Does anyone have any questions about how this machine worked or its impact on society? Let’s discuss!
