one-pound

The compound 'one-pound' is a straightforward combination of the numeral 'one' and the unit 'pound'. 'One' descends from the Old English 'ān', a fundamental numeral in the Germanic language family. 'Pound' entered English via the Latin 'pondō', which is related to the concept of weight, stemming from the Proto-Indo-European root pend- associated with hanging and weighing. The modern compound directly and literally denotes an item with a weight or monetary value equivalent to a single pound, maintaining a transparent semantic link to its constituent parts.

A numeral root of Germanic origin. - pound: From Old English 'pund', a unit of weight and later currency, borrowed from Latin 'pondō' ("by weight") and ultimately from the Proto-Indo-European root pend- ("to pull, stretch; weight").
