spīþra

Old English spīþra derives from spinnan, meaning 'to spin.' A spider is, etymologically, a spinner. This is one of the rare cases where the common name captures the animal's most distinctive behavior with perfect accuracy. Spider silk is one of the strongest known biological materials — weight for weight, some spider silks are stronger than steel and tougher than Kevlar. A single spider can produce up to seven different types of silk, each with a different function: sticky silk for catching prey, dragline silk for structural support, swathing silk for wrapping captured insects.

The Greek word for spider, arachne, gives us the scientific term arachnid. In Greek mythology, Arachne was a mortal weaver from Lydia who challenged Athena to a weaving contest and produced work so perfect that Athena could find no flaw. Depending on the version — Ovid's Metamorphoses, Book VI, is the most complete — Athena destroyed Arachne's tapestry in rage, and Arachne hanged herself. Athena then transformed her into a spider, condemning her to weave forever. The punishment was to keep doing what she was best at.

Spiders appear in creation myths worldwide. In West African and Caribbean Anansi stories, the spider is a trickster figure who outwits larger animals through cunning. The Navajo credit Spider Woman (Na'ashjé'ii Asdzáá) with teaching humans to weave. In Japanese folklore, the jorōgumo is a spider that shapeshifts into a beautiful woman. The spider's web-building — visible, geometric, patient, and lethal — has made it a universal symbol of both creativity and predation.

English kept the spinner. Greek kept the weaver. West Africa kept the trickster. The spider is all three, and the name you choose tells you which quality your culture noticed first.
