pound — verb

Synonym discussion

Sense: noun/1

For the everyday money unit, pound is the neutral standard word. Use it for prices, wages, and amounts: ten pounds, a pound coin. Quid is informal British speech; it sounds natural in conversation, but not in formal writing or exchange-rate news. Sterling is more formal and often appears in banking or international contexts when you need to make clear that you mean UK money, especially in contrast with other pounds. Pence is not a synonym for pound: it is the smaller unit, with 100 pence in one pound. So you say The ticket cost twenty pounds, but The pound rose against the dollar. In casual chat, A coffee costs three quid also sounds natural.

Etymology

LatinOld EnglishMiddle EnglishEnglish

Modern English pound brings together older ideas of weight, money, and striking. The noun for weight and currency comes from Old English pund, from Latin pondo, meaning 'by weight'. That link helps explain why the same word names both a weight unit and a money unit. The verb developed separately from an older Germanic verb meaning 'beat or crush', and later its spelling matched the noun.
