Every time you connect to Wi-Fi, you are tying a knot — at least etymologically. Latin connectere combined con- ('together') with nectere ('to bind, tie'), producing a verb that meant precisely 'to fasten things together.' The root nectere traces back to Proto-Indo-European *ned- (to bind), the same source that gave Latin nodus ('knot,' ancestor of node) and nexus ('a binding, a linked group'). English adopted connect in the mid-15th century, initially for physical fastening: ropes connected to masts, bridges connected to riverbanks. By the 17th century writers were connecting ideas, and by the 19th century telegraph operators were connecting calls. The word proved perfectly suited to each new technology because its core image — two separate things bound into one — never needed updating. The internet age has made connect one of the most used verbs in English, but its meaning has not drifted an inch from what a Roman sailor understood when tying one rope to another.
