To knit means to create fabric by interlocking loops of yarn using special needles. When you knit, you use two long, pointed needles to pull yarn through loops, building row upon row until you've made something like a scarf, sweater, or blanket. People have been knitting for over a thousand years, creating everything from warm socks to elaborate patterns.

Knitting requires patience and concentration. Each stitch connects to the ones around it, so one mistake can unravel your work if you're not careful. But that's also what makes knitting satisfying: you can watch something grow from a simple ball of yarn into something useful and beautiful, one loop at a time.

The word also describes how things join tightly together. When a broken bone heals, doctors say it knits back together. A close group of friends might be called tightly knit or close-knit because they're connected to each other in strong, interconnected ways, just like stitches in a sweater. You might also knit your brow (wrinkle your forehead) when concentrating hard on a difficult problem.
