bee: [OE] Old English bēo ‘bee’ came from a prehistoric West and North Germanic *bīōn, source also of German biene, Dutch bij, and Swedish bi, which may all be traceable back to an Indo-European base *bhi- ‘quiver’. This, if it is true, means that the bee was originally named as the ‘quivering’, or perhaps ‘humming’ insect. Latin fucus ‘drone’ appears to be related.
