drop

drop: [OE] Drop, droop, and drip are closely related. Droop [13] was borrowed from Old Norse drūpa, which came from a Germanic base *drūp-. A variant of this, *drup-, produced Middle Danish drippe, the probable source of English drip [15], and a further variant, *drop-, lies behind Old English dropa, ancestor of modern English drop.

All three go back ultimately to a prehistoric Indo-European *dhreub-, source of Irish drucht ‘dew’. The English noun originally meant ‘globule of liquid’, and its related verb ‘fall in drops’. The main modern transitive sense, ‘allow to fall’, developed in the 14th century, giving English a single word for the concept of ‘letting fall’ not shared by, for example, French and German, which have to use phrases to express it: respectively, laisser tomber and fallen lassen.
=> drip, droop
