spider
蜘 centers on the spider, an eight-legged insect-like creature known for spinning webs.
蜘 combines 虫 (insect) with 知, which likely contributes the sound チ and may have originally referred to a spider-like creature. The exact historical development is uncertain.
The left side 虫 means insect, and the right side 知 looks like a web with a spider in the center. Together they form 蜘, a spider.
For チ, imagine a spider sipping tea: tea -> チ, and the spider holds a tiny teacup in its web.
