10 English idioms about money you should know<\/h2>\n

1. Cost an arm and a leg<\/h3>\n

Senso:<\/strong> very expensive; priced higher than feels reasonable.<\/p>\n

Origine:<\/strong> the phrase began appearing in American newspapers shortly after World War II. One popular theory traces it to soldiers who returned home having literally lost limbs in combat \u2014 those losses became a vivid measure of an enormous, life-changing price. Another theory points to early American portrait painters, who supposedly charged more for paintings that included arms and legs rather than just a head and shoulders. Either way, by the 1950s the phrase was firmly fixed in everyday speech.<\/p>\n

Esempi:<\/strong><\/p>\n

    \n
  • That handbag is gorgeous, but it costs an arm and a leg.<\/li>\n
  • We wanted to renovate the kitchen, but the contractor’s quote was going to cost an arm and a leg.<\/li>\n<\/ul>\n
    \"Saving<\/div>\n

    2. Bring home the bacon<\/h3>\n

    Senso:<\/strong> to earn money to support a family; to be the main income earner in a household.<\/p>\n

    Origine:<\/strong> there are two leading stories. One traces the phrase to a medieval English tradition in the village of Dunmow, where any married couple who could swear they had not argued for a year and a day was rewarded with a side of bacon. The other links it to American county fairs, where greased-pig contests offered a real pig as the prize. By the early twentieth century, sportswriters used the phrase to describe boxers earning prize money, and it spread from there into general conversation.<\/p>\n

    Esempi:<\/strong><\/p>\n

      \n
    • She works two jobs to bring home the bacon while her husband finishes graduate school.<\/li>\n
    • Both partners bring home the bacon in our household, so we split the rent evenly.<\/li>\n<\/ul>\n

      3. Foot the bill<\/h3>\n

      Senso:<\/strong> to pay for something, especially something expensive or unexpected.<\/p>\n

      Origine:<\/strong> the verb foot<\/em> here refers to the bottom or foot of a written bill, where the total appears. As early as the fifteenth century, English speakers used to foot<\/em> to mean adding up a column of numbers and writing the total at the foot of the page. By the nineteenth century, “footing the bill” had drifted from doing the math to actually paying the amount.<\/p>\n

      Esempi:<\/strong><\/p>\n

        \n
      • The company will foot the bill for our hotel and meals during the conference.<\/li>\n
      • When the pipe burst, our landlord had to foot the bill for repairs.<\/li>\n<\/ul>\n
        \"Business<\/div>\n

        4. Money doesn’t grow on trees<\/h3>\n

        Senso:<\/strong> money is not unlimited; it has to be earned and should not be wasted.<\/p>\n

        Origine:<\/strong> this proverb has been recorded since at least the eighteenth century in English, and similar versions exist in many other languages. The image is simple: trees produce fruit freely, year after year, with no human effort. Money does not. Parents have used the phrase for generations to remind children that every dollar represents real work.<\/p>\n

        Esempi:<\/strong><\/p>\n

          \n
        • You want another video game already? Money doesn’t grow on trees.<\/li>\n
        • The CEO reminded the team that money doesn’t grow on trees and asked everyone to cut travel expenses.<\/li>\n<\/ul>\n

          5. Save for a rainy day<\/h3>\n

          Senso:<\/strong> to put money aside for an unexpected future need or emergency.<\/p>\n

          Origine:<\/strong> the phrase dates back to at least the sixteenth century in English, and earlier versions appear in Italian. In agricultural societies, rain was both essential for crops and a symbol of bad luck \u2014 a stormy day could mean lost work or ruined goods. Saving up for that “rainy day” became a metaphor for financial preparation against any setback. The expression appears in plays from the 1500s and is still one of the most quoted personal-finance phrases in modern English.<\/p>\n

          Esempi:<\/strong><\/p>\n

            \n
          • Even though I’m tempted to splurge on a new phone, I’m saving for a rainy day instead.<\/li>\n
          • His grandparents lived through tough times, so they always told him to save for a rainy day.<\/li>\n<\/ul>\n
            \"Foot<\/div>\n

            6. Tighten your belt<\/h3>\n

            Senso:<\/strong> to spend less money; to live more carefully because of reduced income or rising costs.<\/p>\n

            Origine:<\/strong> the imagery is literal. When food was scarce and people lost weight, they had to physically tighten their belts to keep their pants up. Soldiers and labourers used the phrase during the Great Depression of the 1930s, when entire economies were forced into austerity. It quickly moved from describing hunger to describing financial restraint, and today it appears in everything from family budget conversations to government policy debates.<\/p>\n

            Esempi:<\/strong><\/p>\n

              \n
            • Now that we have a baby, we’ll need to tighten our belts and skip the holiday this year.<\/li>\n
            • The whole department had to tighten its belt after the company missed its quarterly targets.<\/li>\n<\/ul>\n

              7. Pay through the nose<\/h3>\n

              Senso:<\/strong> to pay an unfairly high or excessive price for something.<\/p>\n

              Origine:<\/strong> the most colorful theory traces the phrase to the ninth century, when the Danes are said to have imposed a “nose tax” on the Irish; people who refused to pay reportedly had their noses slit. Most modern etymologists are skeptical of that story, but the gruesome image stuck. By the seventeenth century, English writers were using pay through the nose<\/em> to mean paying a price that hurts, regardless of whether anyone’s nose was actually involved.<\/p>\n

              Esempi:<\/strong><\/p>\n

                \n
              • If you buy concert tickets from a scalper, you’ll pay through the nose.<\/li>\n
              • Tourists often pay through the nose for water and snacks near famous attractions.<\/li>\n<\/ul>\n

                8. Break the bank<\/h3>\n

                Senso:<\/strong> to cost more money than someone has, or to spend a huge amount on something.<\/p>\n

                Origine:<\/strong> the expression comes from gambling. In casino games, the “bank” is the pile of chips a casino sets aside to cover bets at a particular table. If a lucky player won so much that the bank ran out of money, the player had literally broken the bank. By the nineteenth century, the phrase had jumped from casinos into ordinary speech, where it now refers to any expense that drains a budget \u2014 usually used in the negative form: “It won’t break the bank.”<\/em><\/p>\n

                Esempi:<\/strong><\/p>\n

                  \n
                • You can throw a great birthday party without breaking the bank.<\/li>\n
                • She found a wedding dress that looked stunning and didn’t break the bank.<\/li>\n<\/ul>\n

                  9. Cash cow<\/h3>\n

                  Senso:<\/strong> a business, product, or investment that produces a steady, reliable income with little ongoing effort.<\/p>\n

                  Origine:<\/strong> the phrase comes from agriculture, where a cow is a long-term source of milk and calves. Business writers in the mid-twentieth century borrowed the image to describe products that, once established, kept generating revenue year after year. The Boston Consulting Group made the term famous in the 1970s with its “Growth-Share Matrix,” where mature, profitable products were officially classified as “cash cows.”<\/p>\n

                  Esempi:<\/strong><\/p>\n

                  • The original game has become a cash cow for the studio thanks to in-app purchases.<\/li>\n
                  • Renting out their second apartment turned out to be a real cash cow for the family.<\/li>\n<\/ul>\n

                    10. A penny for your thoughts<\/h3>\n

                    Senso:<\/strong> a friendly way to ask someone what they are thinking, especially when they look quiet or distracted.<\/p>\n

                    Origine:<\/strong> the phrase appears in writing as early as the 1500s, in Sir Thomas More’s Four Last Things<\/em>. Pennies were a meaningful unit of money in the sixteenth century, so offering one symbolically valued the other person’s silent thoughts. The expression has survived several centuries of currency changes and is still used today, even though a real penny is now nearly worthless.<\/p>\n

                    Esempi:<\/strong><\/p>\n

                      \n
                    • You’ve been quiet all evening \u2014 a penny for your thoughts?<\/li>\n
                    • She stared out the window during the meeting, so I leaned over and whispered, “A penny for your thoughts?”<\/li>\n<\/ul>\n
